I'm running a Windows Server 2003 network and I use ISA Server 2004 SP2 and WSUS.
The problem is that the ISA Server computer does not show up in WSUS (note: WSUS and ISA Server are installed on two different machines, WSUS is installed on port 8530). All other clients in the the network show up normally and can download and install all updates, the issue is just with the ISA Server computer).
I have created an access rule in ISA Server to allow HTTP, HTTPS and Kerberos-Sec (UDP) from localhost to the WSUS computer for 'All Users', but still nothing. The result when running ClientDiag.exe on the ISA Server computer is the following:
Checking Connection to WSUS/SUS Server
WUServer = http://SERVER:8530
WUStatusServer = http://SERVER:8530
UseWuServer is enabled. . . . . . . . . . . . . . . . . PASS
VerifyWUServerURL() failed with hr=0x80072efd
A connection with the server could not be established
When I try to browse to the WSUS administration page (http://SERVER:8530/wsusadmin
), I get a "Cannot find server or DNS error" in IE (note: IE on ISA Server computer is setup to use a web proxy, which is the ISA Server itself).
Thanks in advance
