I had a similar issue with a db application taking 60 seconds or more to open up over a T1 connection.  I remember reading, but cannot remember where, haven’t been able to find it, and I can’t remember if I was researching the same error message, that the extra back and forth that you’re seeing has something to do with SMB checking alternate data streams on the targeted file.  Rather than troubleshoot that, I was able to offer the users an offline solution where the clients would sync at the end of the session, rather than access all the info up front.  Perhaps a solution like that would help?

What is the latency between the two hosts (approximately)?

I am having a problem with slow response over an oc3 wan link using Microsoft office documents, specifically excel documents. The users are attempting to open roughly a 100kb file and takes approx 90 seconds to open.  I sniffed the traffic and have been combing through the frames with Wireshark but I see a confusing pattern. The workstation frequently attempts “NT Create Andx Request” and the server then immediately returns with “Error: Status_Access_Denied”.  This pattern repeats over and over again during this conversation and I suspect it may have something to do with the slow response these users are experiencing. I have spent a lot of time on google trying to determine this and keep coming up empty handed…

 

Does anyone have any insight as to what may be going on here?

 

Thanks,

 

Adam
