Recently I have experienced an unknown problem when playing with 3dsmax. Whenever I try to reset the scene (equivalent to 'Close' then 'Create New File' command in normal app) which has external link to files on server, it halted and Wait Chain Analyzer shown "One or more thread is waiting for Network I/O". 
The whole reset process took about 5 mins to complete if the maxfile are on local (external files still on same network server), it takes less than 1 second. It seems like the 3dsmax software itself doesn't handle network probably? Any tools to trace single program's network or file access activities?
I used Wireshark to analyze the packet transfer between the program and file server, noticed there is a "Notify Response, Error: Status_PENDING" & "Notify Response, Error: Status_CANCELLED" for certain network folders, and it keeps re-sending for 2 or 3 times "Close Request File" before it finally response.
What could have caused this you think? Any suggestion that I can do to trace more info in order to identify what's behind the slowdown?
