So I am guessing that:
198.6.1.1 responded to the pings?
www.yahoo.com did not respond to the pings?
When you ipconfig /all what dns servers are you using? I will check them out. Try to manually put in 198.6.1.1 and 198.6.1.3 in the DNS under your TCP/IP setup and try the ping to www.yahoo.com again.
Thank you so much for you time here.
The ping is not the problem here. Ofcourse the problem, this is not my machine it is one of the users in the network. I am actually having problems re-creating the erros as it only occurs in the morning. The DNS servers are manually put as is the Gateway. I will ask the DNS admins to check out the DNS servers.
My only option now is there are 3 dns in the network information. The first is the domain server, which only works as a domain admin, the second and third is the generic / actual dns. My hypothesis is that the domain DNS takes too much time before it times out, and the webpage / mail / connection times out before the connections get to try the 2nd and 3rd DNS.
I think part of the problem might be connected to the fact that the domain server does not communicate well with DNS 2 and 3.
For the IM, I cant use it here anyways, so there is not use enabling it...still thank you for your time.
Best regards
