"Save as" dialog hanging on certain network folder

[Guest ses1984]

I am trying to troubleshoot a very small business network. There is a folder

 

shared from a Windows XP Pro machine, and when initiating a save as dialog to

 

this location, many office applications will hang when it appears to be

 

loading the contents of the folder. I have tested Excel and Word, versions

 

2000 and 2003. Navigating to the folder in explorer works just fine. I

 

thought rebooting would help, but the issue appears to effect the machine

 

even after a fresh boot.

 

 

 

Some machines on our network behave correctly. Others will hang for a short

 

while but eventually load the contents of the folder. Others will hang

 

indefinitely.

 

 

 

It is always the same machines that have the same type of problem. The

 

hardware between all these machines is comparable but not identical. All the

 

machines are running fully updated Windows XP 32 bit.
