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 --------- access.log excerpt: Tue Dec 2 15:30:36 2003 30 10.10.14.113 TCP_MEM_HIT/200 3592 GET http://windowsupdate.microsoft.com/ - NONE/- text/html Tue Dec 2 15:30:36 2003 32 10.10.14.113 TCP_MEM_HIT/200 2391 GET http://windowsupdate.microsoft.com/redirect.js - NONE/- application/x-javascript Tue Dec 2 15:30:36 2003 102 10.10.14.113 TCP_MISS/302 428 GET http://v4.windowsupdate.microsoft.com/default.asp - DIRECT/207.46.244.222 text/html Tue Dec 2 15:30:36 2003 174 10.10.14.113 TCP_MISS/200 8383 GET http://v4.windowsupdate.microsoft.com/en/default.asp - DIRECT/65.54.249.61 text/html Tue Dec 2 15:30:36 2003 35 10.10.14.113 TCP_MEM_HIT/200 3854 GET http://v4.windowsupdate.microsoft.com/shared/js/Redirect.js - NONE/- application/x-javascript Tue Dec 2 15:30:36 2003 129 10.10.14.113 TCP_HIT/200 22132 GET http://v4.windowsupdate.microsoft.com/shared/js/top.js - NONE/- application/x-javascript Tue Dec 2 15:30:37 2003 51 10.10.14.113 TCP_HIT/200 520 GET http://v4.windowsupdate.microsoft.com/shared/js/top.vbs - NONE/- text/vbscript Tue Dec 2 15:30:37 2003 106 10.10.14.113 TCP_MISS/200 1173 GET http://v4.windowsupdate.microsoft.com/shared/js/survey.js?
