Couldn’t ping user’s computer over the network.
Computer is pingable localy.
Also computer is online and able browse network and internet.
Resolution:
Computer had Cisco VPN client install.
While connecting to the network via Cisco VPN client remptely, computer was pingable over a network without issues.
Reinstalling Cisco VPN client completely seems to resolve the issue.
Windows XP SP2, Symantec AV (enterprise), Cisco VPN client 4.6
I got call from user:
I cannot connect to the VPN. When I try to connect, I receive the following message…
Error 51: IPC failed with error -4h. This is most likely due to the Cisco System Inc. VPN Service not being started. Please start this service and try again.
Resolution:
Found that it is conflict issue between AV and VPN client.
If “Enable File System Real Time Protection” was unchecked (disabled), user had no problems launching VPN client.
Uninstalled AV.
Uninstalled VPN.
