Windows 2000 DC Server Reporting Out of Disk Space

I have an office that has an old Win2K server acting as it's DC, I've started having problems
where it's reporting Out of Disk Space when I attempt to change passwords, create new users etc. Active Directory as it reports it's out of disk space but disk management shows over 2GB free on each of the three drives - I'm working remotely on this server so I don't want to reboot it in case it doesn't come back up.  Any suggestions please?

Clean out your %windir%\Temp, and \Documents and Settings\%username%\Local
Settings\Temp directory.

Delete the Temporary Internet Files, and History.

Also check for the existence of User.dmp and Memory.dmp (both, by default should be in
the %windir% directory) you can delete these unless your going to send them
to the application vendor, or Microsoft for troubleshooting purposes.

Other options are; moving the pagefile to one of the other drives,

uninstall your programs that are installed in C:\Program Files and reinstall them to
D:\Program Files

I'll check those but the issue is that the there appears to be more than enough space available on the drives but this error is being reported in AD which suggests a bigger problem.

Is it the only DC?

Also what is the exact error message?

Yes it's the only DC, the error message is -

The following Active Directory error occurred: There is not enough space on this disk


Windows cannot complete the password change for User 12 because:  There is not enough space on the disk

The server isn't used for much else but I can copy/paste from/to each drive so the problem appears to be directly related to AD
