i am facing this problem since one month. the problem is with my server 2003.
people on network, sometime they are able to ping and access network shares on it, but sometime it does not respond. ping fails and we are unable to access it. after restarting the server also doesn’t effect much. one more thing also when i try to install some anti virus on it it says:-
could not access windows installer even though i have installed 4.5 version of windows installer on it.
