I had a domain controller/Exchange server with a corrupted RAID-5 array so I used Ghost to do a disk clone to another system, and then did a repair install on the clone to get Win2k to recognize the new disk controller. I then reapplied SP4.
In the System Log in Event Viewer, I'm constantly seeing "Remote Access Connection Manager failed to start because it could not create buffers. Access is denied." If I try to start the service manually through Services, I get the same error ("Access is denied.") For now, I just disabled the service, because it was filling up my event log with several entries per second! But I would like to get this fixed.
I did some searching and the only real answers I could find were related to Windows XP service pack 1, which this is not - it's Windows 2000 Server with Service Pack 4.
