two Win2k's won't respond to Ping
Posted on 2004-11-27
We have five machines, three of them XPPro, two 2kPro. The XPPro's are fine. Starting at the end of the day Wednesday (after working fine until then) suddenly the two 2kPro's do not respond to pings (request timed out). They do not respond whether the pinger is XP or another 2k. However each 2k can ping and respond to itself (computername, 127.0.0.1 & IP address).
When I restart a 2k, early in the boot process it responds for a while, but then quits responding shortly after the userid/password prompt appears.
Both 2k's still work fine on the internet (DSL) so they're getting through the switch and out to the router ok.
All are on the same subnet 192.168.0.1. Initially are were DHCP but now one of the 2k's is static (192.168.0.10).
There is no firewall that I know of on the 2k machines. At one time we had StarBand and and Ositis WinProxy on one of the 2k machines, but that has been removed for some time now. At any rate, the other 2k machine never had WinProxy on it.
I removed the three most recent hotfixes that had been applied last Saturday (three full business days before the failure) with no help.
I'm going crazy! What could be suddenly inhibiting ping responses? I'm considering trying an XP Pro Upgrade if all else fails! Thanks for any suggestions! I need this working before Monday!
