Hi, this is a very strange experience I am encountering with Internet sharing but only on one of four computers.
My 4 computer (pc # 1, 2, 3, 4) network is setup using 2 internet cards in desktop PC # 1 doing Internet Sharing, dhcp, etc.
I am using cable Internet. I am using cat5 wired connections with an 8 port small hub to which all computers are connected. Internet Sharing has worked without problems since over 2 years.
Now all of a sudden, I am having this problem
A VERY STRANGE PROBLEM:
1) One of my other desktops PC # 4, that worked all along (WIN XP Pro, SP2) is now taking almost 4 mins to connect to MSN.COM site as well as many other sites. I can go to Google.com in split second access and google search will show results fast as well, however, when I click on the google results hyplinks, most links never work, while one odd one may work after approx 3 to 4 mins.
2) I can go to do my banking services website that uses https and login and do banking and all at very good speed. No problems there...very strange.
3) I can ping to other computers on the LAN and open folders on other computers and do file transfers, no problems.
I can even do remote access from PC#4 to PC# 1 with full control.
4) I cannot open up a pre-saved HTML of a web page saved on my hard drive. However, the same local HTML file will open up fine if I disconnect network cable from the hub.
5) I have looked at firewalls on both PC # 1 and PC # 4 and tried turning off both, but no improvement.
6) THIS IS AGAIN VERY STRANGE...
If I connect directly to the cable modem to PC # 4 , then VIOLA! everything works beautiful and fast with full speed connection as if there is no problem and all websites including MSN.COM work flawlessly. At this point my network card in system tray shows as "Connected at 100 mbps" otherwise it's at 10 when connected via the hub.
7) PC's # 2 and 3, both are laptops and work fine, connected to the same hub and running win xp pro as well.
8) I have tried using cable from other pc's and it does not seem to be a cable problem
9) The only few changes that were done at one point are:
A cisco VPN software was installed recently by my son to connect to his work vpn but it was uninstalled after he discovered he could not get it to work. I am not sure if that did some configurational changes or what.
10) I also cleaned PC # 4 with Ad Aware SE PRO and checked with mcafee for virus,etc - none.
Thanks
