On the Workgroup I have Windows XP SP 3 PCs and along with that I have Windows 7 64 bit PCs as well here. Now I have fixed IPs for all the System here. With XP pc when I go with PING I have seen that they have no issues in doing that; they can ping as well as can see each other, but the issue remain with the Windows 7 PC here. What can be the issue is there something that I will have to do so that Windows 7 and the Windows XP can see each other. Also in addition to this I have seen that Windows 7 new PC can see each other as well here. Please let me know if there is anything that can be done so that the situation here can be handled in a pretty handsome here. Will like to see the replies soon in the case here.
