ISA 2004 Server Logs FTP and PPTP failues with error code 0xC0040011 (FWX_E_IS_BUSY)
Posted on 2008-10-30
I have 2 rules on the ISA Server mangament console that allow Outbound FTP(21) and PPTP(1723). When I attempt to connect to a FTP site, or a VPN connection from one of the client computers connected to the ISA server, the ISA server allows the outbound connection, but fails with the error message "A connection was dropped because there are too many pending connection requests". The error code is 0xC0040011, and a description of FWX_E_IS_BUSY. This was working until about a week ago, but I cannot find any updates around that time that may have caused this to start failing.
