Solution: Webex is not working on windows 7

After deploying the Windows 7 64 bit Enterprise version we had 1 issue where Webex was not working properly.
It was freezing, very slow and display was poor. One of my colleague found 2 work around to fix the problem:

1.Add one registry key( MTU ) at this path:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\Tcpip\Parameters\Interfaces

Now look for the folder in which your IP address and other network related info is  visible:

Now create a new “QWORD(64 bit) value”  or “DWORD (32 bit) value, name it  “Mtu” and give it a decimal value of  value of 1500.

 

2.Set the value of  registry key “EnablePMTUDiscovery” (at  HKLM\System\CurrentControlSet\Services\Tcpip\Parameters\) to 1

I hope this will be helpful to someone.
