Downstream servers not downloading

[Taggs]

My downstream WSUS servers are not downloading the latest approved patches from the Master WSUS server.

I have approved several of the updates on the master server and it says it has downloaded them from the WU site ok. I then synchronzied the downstream servers and it is says it was successful on all of the D-S servers.

All servers now say they need 17.68Mb for 9 files, to download from the Master Server but it does not start to download these. I have run "wsusutil.exe reset" and it checks the files but stops again needing 17.68Mb.

I have two other sites running from this server on port 2000 and port 2001. I have changed the ports and run a sync but still the same. I have also stopped these sites and run a sync but still nothing.

Any ideas?

I've also tried to decline the download of the files and then retry but still nothing. I've also tried to restart the Update and b.i.t.s. services but still nothing.

I think I've narrowed it down to error 502 bad gateway but I'm unsure how to fix this?

Can anybody help?

Do the servers that you're running WSUS on have proxy information set in IE?

No proxy settings need as it is pointing internal.

It has worked fine for the past 4-5 months.

I've had to re-install WSUS on the Master server and all seems to be working OK now. Also had to D/L 3Gb of updates again as when I re-installed using "save updates" the down-stream servers still would not download the files.

Also 'retry download' on the down stream servers and hey-presto!
