Ever since moving to Empower in 2008 we have been plagued with Winsock Errors for eSatin systems. Winsock errors #10055 would prematurely stop runs. Following a recomendation by Waters, we have upgraded the ICS software to 1.20.1018. This upgrade has fixed the 10055 Winsock error specifically, but we still get other Winsock errors (#0, 10038, 10053, 10057, 10060, and 10061). These usually occur upon a users initial connection to a system, before a run is started. The most common we have seen are 10038 and 10057. Has anyone else experience similar problems, or have any suggestions on isolating the issue? We are running Empower 2 (Build 2154), FR4, Service Pack C. Our Network structure is comprised of users connecting to the Empower Server through Empower Clients running on Terminal Servers. Our Instrument Lans are using the alternative IP addresses of 172.16.0.xxx. We are using LACE 32 acquisition servers with two dual network cards for the Instrument Lan.
