TCPIP connection error with E4438C and Signal Studio

I am using Signal Studio for Pulse Building and an E4438C using the TCPIP connection. I make calls to AgtPBAPI_IAgtPBProjectDownloadAndPlayPattern (ActiveX Controller) which was created from within NI LabWindows/CVI with the COM API.
This works great, until I get the following error message from the AgtPBAPI_IAgtPBProjectDownloadAndPlayPattern function:
Unable to read data from the transport connection: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.

My automated test script loop basically looks like:

Loop
AgtPBAPI_IAgtPBProjectDownloadAndPlayPattern (pattern from within a previously created .pbp)
Take a measurement.
End Loop

I realize the problem could have many sources including the test PC (running Windows 7), the corportate LAN, networking switching, etc.  I was just wondering if there is a history of TCPIP connection problems with the E4438C.
