ADSI_IsMemberOfGroup()
While working with Active Directory in IIS/ASP on another web project, we hit upon the problem that the ADSI function IsMember() won't tell you if a user is a member by virtue of indirect group membership. (Where user X is a member of group A and group A is a member of group B... IsMember() will say that X is not a member of B and there's no switch to make it traverse nested groups).
So I hacked up a function called ADSI_IsMemberOfGroup() which, given a NT4-style domain name (e.g. "DOMAINNAME"), the NT4-style username (e.g. "THOMAS") and the name of the group (e.g. "Network Administrators"), will make an attempt to determine if THOMAS is a member of Network Administrators either directly or through nested group membership. It then returns TRUE if it found membership, or FALSE if no membership or an error occured.
Now, the code is rather rough, it uses recursion but doesn't check for runaway conditions (however, the IIS script time-out will kill the page eventually). Also, it's unable to properly search AD for the domain so it makes the assumption that there is only one domain in the directory. If someone can find code to finish out support of multi-domain situations where a SAM name can appear multiple times I'd appreciate it.

MinGW (basic makefile)
First off, make sure you have the GNU Tools for Win32, MinGW, and MSYS installed and working.
Then, create the following makefile in your project folder (note, any indented lines must be done using the TAB character, not spaces):
Once that's finished, and you've changed things like main.exe, module1.c to match your project, open up the MSYS window and type the following commands to compile:
UserName@MACHINENAME ~
$ pwd
/home/UserName
UserName@MACHINENAME ~
$ cd /c/dev/projects/test/src
UserName@MACHINENAME /c/dev/projects/test/src
$ make clean
rm module1.o module2.o main.o

RenByDate v2003.11a (a.k.a. QRen)
Finished up the first (re-)release of RenByDate which is a tool that will rename a file and allow you to insert things like the current year, or the day of the week into the filename. This is actually a re-write of QREN that I wrote back in 1991-1992 and uploaded to the CompuServe forums under the userID of 71750,3724 (and was also part of a larger package called QUTIL1). Back then, I charged $5/seat or $20/server for the package but now I'm re-releasing it under the BSD open-source license.
The old version of QREN was written for the MS-DOS platform (using the MIX C compiler) and used some MIX C specific call as well as not being able to handle longer filenames. During the re-write, I used MinGW and tried to re-structure the code to make for easy porting to other platforms.
Installation is as easy as copying the "renbydate.exe" file to a directory in your Windows PATH. None of the other files are required.
Using RenByDate is pretty simple: renbydate log.txt log_%Y%m%d_%H%M.txt will rename "log.txt" to "log_19921021_1455.txt" (if the date/time is currently Oct-21-1992 at 2:55pm). Or you can specify that it should use the timestamp of the file by putting the "-f" switch in. If you're using it inside of a batch file, you'll probably need to double-up the '%' signs (e.g. %%Y%%m%%d) because MS-DOS/Windows likes to interpret '%' signs differently then when you're using the command at the command prompt. As with the original version, it only handles single filenames and will choke on wildcards.
Download:
renbydate-2003.11a.zip - 10KB, Win32 (README.TXT and LICENSE.TXT)
renbydate-2003.11a-source.zip

Getting Started with MinGW
Getting started with MinGW
So I'm trying to dust off my very rusty (and crusty) C and C++ skills and I've downloaded the MinGW compiler and the MSYS package. On the plus side, compiling with MinGW means that you don't need the Cygwin stuff in order to distribute windows-only binaries - but on the down side, MinGW has very little documentation (I have yet to find a central site). I guess you could try the GCC home pages since MinGW is a port of the GCC compiler collection.
Anyway, it took me a bit to figure out how to compile and link a C application where I have (1) module (usage.c and usage.h) and (1) program (main.c). To compile this into a working .exe file requires the following steps if you're doing it by hand:
gcc -c -o usage.o usage.c
gcc -c -o main.o main.c
gcc -o main.exe main.o usage.o
Now that I know those basics, I need to remember how to use makefiles...

OpenSTA Load Testing Tool
OpenSTA is a decent tool for testing out websites. The learning curve for it is a bit steep until you manage to figure out exactly what bits are which and how to do a simple test. However, it was good enough to test a web application that I wrote at work that depends on a value passed back and forth to maintain session state (rather then depending on a server-issued session cookie).

Enterprise Backup Software
We're currently running NovaNet8 Alliance at work for our tape backups, but we're looking to upgrade to gain some additional features that weren't in 8.00. Unfortunately, they won't let us upgrade to 8.50 which would serve our needs but are forcing us to upgrade to v9 - and they've changed the licensing model so we'll have to pay twice as much for the upgrade compared to previously.
So now we're ticked off - and since NN8 seems to be really finicky about whether or not it will successfully backup to tape every night anyway, we're exploring alternatives. So here's the short list of the products that I know about that support tape, backup to disk, multiple O/S (Windows, Netware at the moment), do media management. Basically, enterprise level backup software. It also has to support our Sony SDX-500C AIT2 tape drive (NovaNet 8 didn't bother reading the AIT memory chip, and just played the tape like a dumb tape).

NovaNet by NovaStor
Backup Exec by Veritas

STOP C000026C
Ewwww, ne'r rains but it pours. Installed the latest Windws Update from MS for my Windows 2000 Server (fixes the DirectX flaw by upgrading to 9.0b) and upon reboot was presented with:
STOP: C000026C Unable to Load Device Driver ... \redbook.sys
Which according to Microsoft's web site supposedly means that there's a damage device driver on the hard disk. My copy of redbook.sys was dated Jun-19-2003 and was 35,344 bytes - on the other Win2K server it's 35,344 bytes. So it's the same size, but perhaps not the same content.
One solution says to boot the setup CD, then go to Recovery (R) and Console (C), pick the number of the installation you wish to use and enter the administrator password. Then type disable xxxxxx.sys where "xxxxxx.sys" is the name of the driver that failed.
Well, I got an error saying that it couldn't find the registry entry for service redbook.sys. I also was unable to copy redbook.sys from \WINNT\$NTServicePackUninstall$ and get it to boot. So finally, I renamed redbook.sys to redbook.bad and got the server to boot.
Not 100% sure what the next step is - guess I'll try copying the redbook.sys from the other Win2K server and see if I can get a boot. (But first, I'll update my ERDs!) -- Well, copying the file from the other server results in BSOD again, so the file that I had on the hard drive was already the proper file. That points to registry as the problem (probably have to uninstall/reinstall the CD-ROM driver as a guess).
So, searching through the registry on the other server for "redbook.sys", I see it occuring under a key that also has "Digital CD Audio Playback Filter Driver" as a value (good find), as well as entries under the EventLog where the different events are defined by the various applications (not important find). Kind-of confirms my guess that I'll need to uninstall/re-install the CD-ROM drivers.
Uninstalling/reinstalling CD-ROM caused the error again. pcAnywhere is also refusing to load the host service when I try to remote in rather then stand at the console. At this point, I've renamed the driver file again, have the system booted up and I'm going to spend some time doing backups and getting the data safely stored before I try other things. (This is my 275Gb RAID5 box, so I'll be rather peeved if I have to rebuild it or I should happen to scramble the disks. I already use an external 120Gb USB2.0 drive as a backup for the contents, so I'd never lose more then a single day.)
Update: Ultimately, I never managed to find/fix the root cause of the issue. Renaming redbook.sys out of the way using the Recovery Console allowed me to boot the server and continue using it normally except for functionality provided by redbook.sys. The server finally crashed hard over the Labor Day weekend requiring me to rebuild it anyway.

Really Large Cheap Storage
Promise's SX8000/RM8000 unit which holds (8) IDE drives in a RAID5 configuration, total cost for 1.5Tb of storage was $3.44/Gb.
Well, they also make an RM15000 unit ($4000) which holds (15) IDE drives. Figure (1) drive for the parity bit and (1) drive for a hot-spare and you have theoretical capacity of 3.17Tb at a cost of $2.62/Gb. Using the 160Gb drives (currently $160 each in bulk) you'll end up with a 2.03Tb array at a cost of $3.08/Gb.
FYI, the largest SCSI drive on the market is 180Gb at a cost of $1300 each, so figure the cabinet and hardware to hold the drives would be $2000, and total drive cost of $19500. Resulting cost for 2.28Tb of storage is $9.21/Gb -- which is 3x the cost of the equivalent IDE solution. But the SCSI solution is more suited for primary storage (speed, reliability, warranty).

Gigabit Ethernet
Prepare for Gigabit Ethernet networking
By Brian M. Posey, TechRepublic, March 19, 2003 -- Good article explaining some of the pitfalls about the move to gigabit ethernet.
So I'm getting ready to switch over to Gigabit Ethernet both here at home and at work. Netgear makes an 8 port hub that is only $600 or so (NetGear 8-port Copper Gigabit Switch, GS508TNA) and the ethernet cards are only $125 or so. I've been doing some bench testing of read/write speeds to my local drives vs across the network, and even on an empty (just me and the server) ethernet segment I'm only seeing throughput of 2.0-2.5 Mb/sec when average over a 5 minute interval. The servers on the other hand are able to provide 8-20 Mb/sec reads and 4-12 Mb/sec writes (IDE drives, SCSI drives are 40-50 Mb/sec read and 6-10 Mb/sec writes).
My goal for the office is to switch over to gigabit between the hubs with gigabit to the servers.

How much is that Terabyte in the Window?
We've been considering switching to using a huge array of IDE drives instead of backup tapes for the office (tape drives being notoriously fickled unless you baby them *every* day). Anyway, I priced out a low-cost, secondary storage system to get a feel for pricing.
SuperMicro SC830 server case (pedastal style). It has (9) externally accessible 5.25" drive bays, 2x400W power supply, (3) 3.5" bays and is only $750. The case design looks very good, plus since the 5.25" drive bays are external, I can use the Promise SuperSwap 1000 drive bays ($80) to get hot-swap capability. Add in the Promise SX6000 raid card ($300) and I can chain together (6) ATA/100 drives. Figure about $750 for guts (CPU, RAM, MB) and $750 for the O/S.
$750 SuperMicro SC830 server case
$750 CPU, RAM, MB, etc.
$750 O/S
$300 Promise SX6000 raid card
$640 (8) SuperSwap 1000 bays
$160 (2) 80Gb HDs for the O/S and Apps
----------
~$3500 base cost
IBM 120Gb $140x6 = $840 - net 480Gb $9.04/Gb
IBM 180Gb $220x6 = $1320 - net 720Gb $6.67/Gb
WD 250Gb $320x6 = $1920 - net 1000Gb $5.50/Gb
So, for about $5500 you can setup a server that will house 1000Gb of secondary storage using plain old IDE drives. Pricing using SCSI drives would be around 3x that as a rough guess.
There's also the alternative of using one of the Promise Tech external SCSI-IDE RAID units, which will house (8) IDE drives and connects to the SCSI port of the server. Pricing for the Promise SX8000 unit is $2600, but all you need to add then is (8) IDE drives. This is actually a lot cheaper as you're able to make the array 50% larger by just adding 2 more disks. Personally, I like the idea of the external unit because you don't have to fiddle with setting up another server and the cost per Gb really drops.
IBM 120Gb $140x8 = $1120 - net 720Gb $5.17/Gb
IBM 180Gb $220x8 = $1760 - net 1080Gb $4.04/Gb

Pricing for the Promise SX8000 unit is $2600, but all you need to add then is (8) IDE drives. This is actually a lot cheaper as you're able to make the array 50% larger by just adding 2 more disks. Personally, I like the idea of the external unit because you don't have to fiddle with setting up another server and the cost per Gb really drops.
IBM 120Gb $140x8 = $1120 - net 720Gb $5.17/Gb
IBM 180Gb $220x8 = $1760 - net 1080Gb $4.04/Gb
WD 250Gb $320x8 = $2560 - net 1500Gb $3.44/Gb
