Lost Connection WSAEWOULDBLOCK and WSAEALREADY errors

Hello All,

I need help from all the great minds of the Clovertech Community.  We at Owensboro Medical are having a thread lose connection at random intervals.  The connection is between our engine (Windows 2000 server SP 3) and our Dietary system Vision (Windows 2003 server SP 2).  Then Connection is over a TCP/IP VPN line. I’ve seen a couple of posts with connection problems over VPN’s but no solutions.  Our connection was working fine until Vision upgraded 2003 from Service Pack 1 to Service Pack 2. I can keep the interface up but the port shuts down for no apparent reason. I can’t tell if it’s a timeout issue or not. These messages are from the process log. I noticed the WSAEWOULDBLOCK and WSAEALREADY errors in the log.

My question is if anyone has seen this before?  Any suggestions would be helpful.  I strongly believe this is a Windows issue, I just don’t know how to resolve it. I had to borrow my coworker’s username, sorry for any confusion

Thanks again,
