I am having this problem with ISA using FW clients I have one site and content rule and one protocol rules , when these two rules applies to Any Request everything works fine with me. When these two rules apply to Domain Users I start having problems. Please see below site and content rule :- Name Scope Description Action Applies To Schedule Destination Content Allow rule Array Allow domain_name\domain users Always All destinations All Protocol rules: Name Scope Action Description Protocol Applies To Schedule all Array Allow All IP traffic domain_name\domain users Always c-ip,cs-username,c-agent,sc-authenticated,date,time,s-svcname,s-computername,cs-referred,r-host,r-ip,r-port,time-taken,cs-bytes,sc-bytes,cs-protocol,cs-transport,s-operation,cs-uri,cs-mime-type,s-object-source,sc-status,s-cache-info,rule#1,rule#2,sessionid,connectionid w.x.y.z, username, Morpheus.exe:3:5.0, Y, 1/24/2002, 19:47:33, fwsrv, ISAservername, -, -, 140.107.62.129, 1214, 22907, 0, 0, 1214, TCP, Connect, -, -, -, 10065, 0, all, Allow rule, 11, 207 w.x.y.z, username, Morpheus.exe:3:5.0, Y, 1/24/2002, 19:47:33, fwsrv, ISAservername, -, -, 216.47.144.160, 1214, 22937, 0, 0, 1214, TCP, Connect, -, -, -, 10065, 0, all, Allow rule, 11, 208 w.x.y.z, username, Morpheus.exe:3:5.0, Y, 1/24/2002, 19:47:34, fwsrv, ISAservername, -, -, 65.24.46.194, 1214, 22968, 0, 0, 1214, TCP, Connect, -, -, -, 10065, 0, all, Allow rule, 11, 209 w.x.y.z, username, Morpheus.exe:3:5.0, Y, 1/24/2002, 19:47:34, fwsrv, ISAservername, -, -, 24.150.167.249, 1214, 22984, 0, 0, 1214, TCP, Connect, -, -, -, 10065, 0, all, Allow rule, 11, 210 w.x.y.z, -, -, N, 1/24/2002, 19:47:35, fwsrv, ISAservername, -, -, 10.10.10.143, 445, -, 0, 0, 445, TCP, Connect, -, -, -, 13301, 0, -, Allow rule, 13, 234 w.x.y.z, -, -, N, 1/24/2002, 19:47:35, fwsrv, ISAservername, -, -, 10.10.10.143, 445, -, 0, 0, 445, TCP, Connect, -, -, -, 13301, 0, -, Allow rule, 13, 235 w.x.y.z, -, -, N, 1/24/2002, 19:47:35, fwsrv, ISAservername, -, -, 10.10.10.143, 445, -, 0, 0, 445, TCP, Connect, -, -, -, 13301, 0, -, Allow rule, 13, 236 w.x.y.z, -, -, N, 1/24/2002, 19:47:35, fwsrv, ISAservername, -, -, 10.10.10.143, 445, -, 0, 0, 445, TCP, Connect, -, -, -, 13301, 0, -, Allow rule, 13, 237 w.x.y.z, -, -, N, 1/24/2002, 19:47:35, fwsrv, ISAservername, -, -, 10.10.10.143, 445, -, 0, 0, 445, TCP, Connect, -, -, -, 13301, 0, -, Allow rule, 13, 238 w.x.y.z, -, -, N, 1/24/2002, 19:47:35, fwsrv, ISAservername, -, -, 10.10.10.143, 445, -, 0, 0, 445, TCP, Connect, -, -, -, 13301, 0, -, Allow rule, 13, 239
