Hi,

I have a winXP Pro SP3 with IE8 laptop
We have also 2 internet connection (ISP-1 and ISP-2)and a Sonicwall pro 2040. ISP-1 connection we use for servers only and ISP-2 for users.

When laptop is on ISP-2 WUS won't work, but when using ISP-1, this will work.
Strange thing is all other network computers using ISP-2 can perform update. So i don't think this is a firewall issue.

following the error code on WUS page, it informs me that it's an connection problem, trying other solutions on the net didn;t resolve it.

Has anyone any ideas what is goin' on or anything else i can try?

Did you get the connection error from the PC that failed? There is a folder called softwaredistribution under the C:windows folder. In it is the log that the update client writes to when it checks for updates. Look at that, and see what error code it returns when it cannot connect.

But none of them solved the problem.

Testing with another internet connection helped updating the computer without any errors.
Using another PC on the same subnet was succesfull.

It seems that there;s something when using this interconnection will block this PC from updating.

Are your network pc's on a different subnet than your servers? How does your gateway configs work for these machines?

by arujammer

We have different Subnets (VLANS),servers and PC are on the same VLAN but use different internet connection, our SonicWall is the gateway for all these subnets, every VLAN is configure in the Sonicwall with gateway 192.168.xx.254

No proxy on the vlan that is failing..correct? The only thing I can think of is a access list on your sonic wall that is blocking a port that WUS uses. I think it only uses 80 and 443. I dont think the issue is on the client machine since it works on the other vlan. Either a route issue or an ACL issue. Compare the two and see if you can find any differences. Another thing to check..using command prompt type netstat -no and see what ports it is trying to connect as you try to use WUS on each vlan and then compare what ports are being connected to. Hope this helps.

I use another PC in the same VLAN using the ISP-2, and this PC can update without any errors. Also tried to change LAN IP but same result.

UPDATE: Strange enough e tried open the update page with ISP-1, i got all available downloads, then i switch to ISP-2 and downloaded/installed the selected updates, without any problems. Seems the error is when i tried to load the update page. Something is holding it back from loading when only on ISP-2
