Clients unable to connect to WSUS server

By mkoskenk ·
Recently I started experimenting on the WSUS since I thought it'd be a good way to preserve the bandwidth. I successfully set it up on the development server and got clients to connect there no problem.

Since I installed the WSUS on our production server the clients cannot access it anymore.

--------
Problem: Client connection to WSUS server fails with error code 0x800710dd
--------
Details:

-WSUS installed on server called sorvi, port 8530
-WSUS server pointed by GPO (both update and statistic server): http://sorvi:8530
-IUSR_SORVI is member of USERS group
-USERS group has read, execute and list permissions under following areas in IIS:
*Default Web Site
*Default Web Site/content
*Default Web Site
*WSUS Administration
*WSUS Administration/Content
*WSUS Administration/SelfUpdate
-USERS group has read, execute and list permissions in c:\Program Files\Update Services folder
-GPO is distributed correctly, validated via GPresult on clients
-accessing http://sorvi:8530/selfupdate/wuident.cab from browser produces You are not authorized to view this page (HTTP 401.1) error page
-however, connecting to same address without port specified (http://sorvi/selfupdate/wuident.cab) allows the wuident.cab file download
-Under my development environment I'm using XP SP3 and Vista Business SP2
-I'm able to connect to the WSUS server from my Vista desktop through WSUS management console

I tried pointing to WSUS server http://sorvi without the port number but had no luck there either. I've googled around and most of the offered solutions consern the permissions which (by my understanding) should be correct. If anyone can spot something here please let me know. And please ask for more information if I left something out.

Cheers,
Mikko

Solved!

by mkoskenk In reply to Clients unable to connect ...

As usual, as soon as you post a forum entry, you'll bump head first onto the solution. I had to perform two steps in my case:

1) I changed the permissions on my WSUS Administion web page on IIS as per instructions on http://www.wsus.info/index.php?showtopic=5928&view=findpost&p=23857 and restarted the IIS

2) On my XP desktop I had to reinstall automatic updates client with /wuforce switch. The latest version of the updater is available from Microsofts site: http://technet.microsoft.com/en-us/library/bb932139.aspx

My Vista client was able to connect to the WSUS server after step 1. Hope this helps out someone out there :)
