On one pc I am fixing for a friend,I canot connect to the internet through IE6. I can connect through the CompuServe PPPoE client and can connect to AOL, but can only browse the web from Compuserve. WinXP Home/SP2 installed. I can release and renew my ip from my router and have dns resolution when pinging Yahoo.com. I can browse and attach to a local network share on my server as admin.
Firefox when downloaded and installed did not work either. Originally I could not repair tcp/ip from the command line using netsh init ip repair and would get rpc server unavail. and could not use the disk manager in admin tools/component services without getting the same error. I even cloned this drive and did an in place upgrade of XP with no change in symptoms. BTW I did set IE back to all default settings and have disabled Windows firewall. Zone Alarm is not installed, but had been previously. The funny thing is that the True Vector service still is trying to start and will not let me make any changes to the service. I have no idea what may have uninstalled or deleted on this machine.
I did a repair on my nic interface both automatically and from the command line(flush dns cache/registerdns etc.) I have scanned for virus/trojans/spyware and have eliminated several problems. I have taken off SP2 and reloaded SP2, I have reloaded IE from the command line.
I have tried various IE and tcp/ip fixes given through links on this site. I have scanned my system files with scf/scannow (no problems). I am probably leaving out a lot of proceedures tried due to typing too may words in my post. I can reload XP on another drive and everything connects to the internet properly, so I know that I have an O/S problem and/or registry problem most likely. I even used a registry/system problem program that found over 200 problems. Thought my problem would be resolved....No Luck.
Some of my issues have had to have been resolved because I can now use admin tools/component services/disk manager and can do the netshell repair of tcp/ip from the command line with no errors such as "The RPC servir is unavailable".
Nothing tried to date will allow me to connect to the internet through IE. Any suggestion will be appreciated as I am at this time ready to pick up my trusty axe handle and put this machine out of it's misery.
