Help with 1205 failed to create virtual adapter

I have been pounding my head trying to figure out why I keep getting this error. System is Win 7 64. I have tried uninstalling and reinstalling. The install file shows eveyrthing works fine. When I try to connect I always fail with 1205. Any help would be appreciated. 

 

Thanks.

Re: Help with 1205 failed to create virtual adapter

Hi Mike,

I have seen this issue. On most clients I have to uninstall pulse, any other vpn client, and anything else loaded into the driver stack.

Then run from an admin cmd shell
netsh int ip reset reset.log
netsh winsock reset

Reboot and reinstall.


Hope this helps.

Hi,

 

You can refer below kb and see if it helps.Also Pulse 5.0r3 has NIS6 driver so you can test that :

Check if you are using any Encryption on the laptops, like Bcrypt. You need to whitelist Junos Virtual Adapters from the allowed list of Network adapters.

 

hopefully this will work.

Re: Help with 1205 failed to create virtual adapter

Cause 1: You have exceeded Windows' virtual adapters limit
Solution: Change le value of MaxNumFilters to 14 decimal in the Registry:
HKLM\System\CurrentControlSet\Control\Network

Cause2: 3rd party Antivius or Firewall
Solution: Create an exception for Pulse exe files (c.f. Client changes document). Otherwise, disable or for some cases uninstall firewall or antivirus.

Cause 3: In device manager, if the Juniper Networks Virtual adapter Manager has a exclamation mark, it's most probably Windows that denied the installation of the Juniper driver's signature.

Solution: reboot PC and enter Windows' advanced startup options and choose "Disable Driver Signature Enforcement". Repair Pulse Secure and launch connection.

I hope this helps.
