I am having a strange problem on a Windows 7 machine in that I cannot ping unless I do it from a command prompt that has been run as Administrator. When I try to ping as a standard user and this is the error I get:
> ping 127.0.0.1 Pinging 127.0.0.1 with 32 bytes of data: PING: transmit failed. General failure. PING: transmit failed. General failure. PING: transmit failed. General failure. PING: transmit failed. General failure.
When I run the same command from an instance of cmd.exe started "As Administrator" ping works as expected.
I have searched over the group policy settings and through the entire registry and cannot find what might be causing this.
Here is what I have tried so far (rebooting after each change in setup):
- Verified that the windows firewall is off
- Verified that there is no AV running (not even installed)
- Verified that Microsoft Security Essentials is off
Tried all of the following command line commands:
- netsh int ipv4 reset reset.log
- netsh int ip reset resetlog.log
- netsh winsock reset catalog
- ipconfig /renew
- ipconfig /flushdns
I Have verified/toggled the following registry key values:
- HKLM\System\CurrentControlSet\services\Tcpip\Parameters\EnableICMPRequest = 1
- HKLM\System\CurrentControlSet\services\Tcpip\Parameters\EnableICMPRediredt = 1
- HKLM\System\CurrentControlSet\Control\Lsa\restrictanonymous = 0 (tried 1 too)
I have verified/toggled the following group policy values:
- Computer Configuration\Windows Settings\Security Settings\Local Policies\ User Rights Assignment\Access this computer from the network: Added non-admin users
I also did tried the following steps without success:
- Reboot into safe mode
- Create a new standard user and try from that account
- Unplug all network cables and disable all network adapters
- Ping from admin works for 127.0.0.1, standard user gets same error.
- Turn PXE off for the NIC in the BIOS
I am at my whits end on this one and could really use some help!
** Edited to add more things I've tried.
Edit 2, add some retyped output from route print
