I have a peculiar issue. I work for a governmental agency that is still using XP. An end user contacted me about system hangs. After running diagnostics on the system (Dell) there appeared to be a problem with the hard drive. So, instead of replacing just the drive, I found a newer system and re-imaged it. I stress tested it with Heavy Load and it passed with flying colors.
I then brought it back out to the floor and reconnected all cabling and placed it on the network. I had the user login and all was fine until afternoon. The new machine started hanging! I then observed what the end-user was doing and found that the problem was somewhat intermittent but fairly predictable. Whenever she opens up a mapped drive and accesses certain folders and files, the system hangs. It completely locks up with absolutely no activity whatsoever.
The odds of it being the system are slim, so I concentrated on her roaming profile. I renamed the one on the system to .old and configured the registry to clean up roaming profiles after log off. She pulled down her roaming profile but this did not work either.
She can logon to any other machine and apparently work fine with no issue. I am beginning to think it maybe the port her system is patched to. I also noticed a startup script that was failing on DNS issues. I can't remember exactly what it said, but it pertained to port 53. I blew that off because she can still access the shares and the Internet. But I can't say that I have ever examined the script or what its purpose is.
Any Suggestions are appreciated.
