The company’s environment is such that all client computers use ISA server2006 proxy to access the Internet via an internal WSUS server (172.16.160.236) update patch, and some computers have ISA firewall client software installed.
The windows 7 computer on which the problem was found had the ISA firewall client installed on it.
Solution.
On this problematic windows 7, open a cmd command prompt window and type.

 netsh winhttp set proxy proxy-server=”http=isasvr.xxx.com:8080″ bypass-list=”172.16.160.236″

The effect of the above command is that the communication with the internal WSUS server does not go through the ISA proxy server, i.e., it is updated directly from the WSUS server.
