Hello all
iam facing a strange problem i never meet before and search alot and i find nothing
i have a domain server in our company and most of computers are windows Xp and some are 7 and server windows 2008
one day i find some of my application which i manage the computers with it is not working like goverlan and any application using Ping command thats i cant see the XP computers while i can see all windows 7 and windows server computer .
and also i cant ping these computers ( the xp computers only) but i can access it on network as normal and all users also do and they can print and scan normally .
and to be more strange 2 XP computers only are working ok and the rest about 15 have this problem .
note :
all firewalls are offline and nothing changes on them (windows firewall and firewall application )
what can i do?
or i have to upgrade to windows 7 to fix it? i wish i can know the reason
