SCCM and WSUS Sync issues
I have configured SCCM to prompt WSUS to go out and look for available updates however when I check the logs and the WSUS server it has the nice 407 Proxy Authentication Required error. The weird thing is that if I change the settings in the ConfigMgr software update point say remove the check in the Use credentials to connect to the proxy server I can get it to do numerous successful sync’s for a while then it just stops and spits the 407 error back up, Once this has happened I can go back in and add credentials and most of the time it will again start working for a while and again after an hour or so stop.
Does anyone have any idea as to what might be causing this or what further information I can provide that might help
System setup is as bellow
Blade server array
Server installed on a VMware esx
Server itself is windows 2008 R2
SCCM and WSUS are located on the same server.
Any help would be great
