Running Windows 7 SP1 x64 fully patched. As of a few days ago I can no longer access, via http, telnet, ping a specific IP address. I can access everything else on the network, whether it be LAN or WLAN.No updates, computer changes or installations between this working and not working.
IP address that I can't get to is valid (one of our A5500 Switches) and in same range, no access via IE, Firefox or Chrome. Cannot telnet, or ping, no blocks in place, nothing in firewall, have even turned firewall and AV off. Nothing in host/lmhosts. Nothing apparent in NIC Intel 82578DM (latest driver). Nothing on far end (IP trying to get to) blocking stopping my IP, though this has also been changed.
Can't access from my machine using another username/profile, have tried static and DHCP assigned IP address on machine.
CAN access from any other machine and with my profile on other computers.
Totally bizarre. Thanks for any pointers/help.
