Usually when HTCondor daemons exit in this manner, it is because the system in question has a non-standard Winsock Layered Service Provider (LSP) installed on it. An LSP is, in effect, a plug-in for the TCP/IP protocol stack. LSPs have been installed as part of anti-virus software and other security-related packages.

There are several tools available to check your system for the presence of LSPs. One with which we have had success is LSP-Fix, available at http://www.cexx.org/lspfix.htm. Any non-Microsoft LSPs identified by this tool may potentially be causing the WSAENOTSOCK error in HTCondor. Although the LSP-Fix tool allows the direct removal of an LSP, it is likely advisable to completely remove the application for which the LSP is a part via the Control Panel.

Another approach is to completely reset the TCP/IP stack to its original state. This can be done using the netsh tool: 

netsh int ip reset reset-stack.log
The command will return the TCP/IP stack back to the state is was in when the OS was first installed. The log file defined above will record all the configuration changes made by netsh.
