Hi ! I'm fairly new to ISA so I wonder if one of you could help me with this. I'm running ISA Server 2000 on my SBS2003 Server. I've been trying to set up rpc over http as this would be a really useful tool for my users. However I get as far as entering my username and password then it just hangs. I checked my ISA Logs to find 2004-11-06 19:18:01 80.47.216.2 217.52.205.34 Tcp 3556 81 SYN BLOCKED 217.52.205.34 45 00 00 30 9b e7 40 00 6e 06 a2 66 50 2f d8 02 d9 25 cd 22 0d e4 00 51 89 03 8b 58 00 00 00 00 70 02 20 00 72 14 00 00 02 04 05 b4 01 01 04 02 which was my attempted connection, and from the other log 80.47.216.2 anonymous MSRPC 2004-11-06 18:40:38 HQ-SERVER - www.mydomain.com 192.168.0.1 443 78797 373 552 http RPC_OUT_DATA http://www.mydomain.com:443/rpc/rpcproxy.dll?hq-server.mydomain.com:6004 Inet 1115 80.47.216.2 anonymous MSRPC 2004-11-06 18:40:38 HQ-SERVER - www.mydomain.com 192.168.0.1 443 83047 870 - http RPC_IN_DATA http://www.mydomain.com:443/rpc/rpcproxy.dll?hq-server.mydomain.com:6004 Inet 1115 Can anyone please tell me why this was blocked and how to let it through. Many thanks in advance Ian
