I suspect that you need to add RAM to your system. 64MB is just not enough for Win2K. 256MB to 512MB is much better for an NT operating system.
This kind of error normally only occur in Win9x, which requires editing the System.ini file, such as described about halfway down the middle of this <A HREF="http://www.monsterworks.net/computerstuph/snaphoos.htm" target="_new">page</A>. But the Win9x "fix" isn't applicable in Win2K, so your only option may be additional RAM.
A second concern is that this error may also associated with a problematic device driver. I'd check the Event Viewer logs for any evidence of this, and update the drivers for my devices, including the chipset, and any patches for the operating system from Windows Update.
If you upgraded from Win9x to Win2K, you also might consider a clean, full installation, as upgrading often causes Win2K to function in an unstable condition, and this can include lockups, memory errors, and compatibility issues with various programs, especially games.
