Hi all.. I know that this is not the answer that you are looking for, but why not just install a WSUS server internally? Then point all your clients to it via AD policy. (me being a lazy bugger here!)

Lucky you, looks like you have a good up-to-date user base then :). Mine have trouble in WinXP SP1 and some earlier versions of the ActiveX WU'er they call MicrosoftUpdate. GenuineAdvantage my a*%#. > > Reinhard > IIRC others earlier found that WU used range requests to speed downloads. I have never confirmed this myself. Anyway, a bug has just been found in 3.0.RC1 that caused certain range requests to close prematurely. http://www.squid-cache.org/bugs/show_bug.cgi?id=2116 A fix has been incorporated in the next daily snapshot. If anyone is having this problem with 3.0.RC1, please give the 31 Oct or later snapshots a try and see if that fixes your problem. If its still present it will need to be reported as a bug with traces, etc. Thank you.
