[squid-users] Windows Update Problem

Greetings All,

We have experienced an interesting problem with Windows Update. Essentially, the service fails when the client (W2K / IE6) uses the proxy server and succeeds when it bypasses the proxy. After you click "Scan for Updates" the web server replies with something like (sorry I don't have the exact error in front of me) "an unknown error has occurred". The access.log and cache.log don't show anything out of the ordinary (access.log excerpt is below).

I have gotten around the problem temporarily by including:

acl windowsupdate dstdomain .windowsupdate.microsoft.com
no_cache deny windowsupdate

in squid.conf

The mailing list archives have some similar problems that point to cache_dir being too small (running out of cache space) but I don't believe that is my problem:

cache_dir aufs /usr/local/squid/cache0 48000 16 256
cache_dir aufs /usr/local/squid/cache1 48000 16 256

#df -h|grep cache
/dev/sdb1 67G 37G 27G 58% /usr/local/squid/cache0
/dev/sdc1 67G 37G 27G 58% /usr/local/squid/cache1

#./squid -v

Squid Cache: Version 2.5.STABLE1-20030102
configure options: --enable-storeio=ufs,aufs,diskd --enable-snmp

Any suggestions would be most welcome.

Thanks,

Grant
