Lost space on my c drive

if it's a server, no need to have an hibernation file, so you can already reclaim that space by issuing the following command :
powercfg -H off

if you have another drive, you could also move the swap file (which is managed by the system by default, so that's maybe where your free space went) to that other drive. For that, go to <contral panel><System><advanced system settings><performance settings> then click on the <advanced> tab and you will find a button to change the virtual memory settings ...

Hope that helps

Possibly some log files taking up space. Use TreeSizeFree to scan the system and find out what's hogging all the space:

There have been numerous blogs lately about various logs suddenly taking up space. The following article states for SBS 2008, but much of it applies to 2003 as well:

Also if you have not run an Exchange backup, probably using the SBS backup tool, the Exchange logs and deleted items get very large. These can be cleared simply by running a backup.

It could be your config log in IIS, or any other number of things.

A good program to let you see what's taking up your space is WinDirStat:

Looks like the issue is a Wsus Database.  An sql database can I compact it?

Ok, I know I will sound like an idoit but how do I get the program to run.  When I run click on it, It flashes and goes away.  When I use comand prompt, I can not get to the file to run.  How do I access it?

Ok, I got to wsusutil nowmbut I am having an issue
my command is:

wsusutil movecontent d:\Wsusdatabase d:\Wsusdatabase\wsus_mov.log

I get an error saying: Fatal Error: You must specify an existing local directory on an NTFS partition as an absolute path or specify an exisitng UNC path for the new content file location.

The D drive is a NTFS local drive

Did you create the folder "d:\Wsusdatabase". It must exist before you run the command.

yes the folder exisits

Very odd. I actually have never specified the log file location, or changing the folder name, but perhaps try:
wsusutil movecontent d:\WSUS d:\wsus_mov.log
D is a local drive not a network/mapped drive I assume.

it says it is moving the content now.  After it is all moved can I delete the file on the C drive?

Yes but look at the moved folder and only remove the matching files/folders. There is usually a folder with a few items you still have to leave behind. Doesn't take much space at all.
