Citrix connection hangs on 'Negotiating Capabilities'

This is an annoying issue that occurs in an inconsistent manner. Fortunately the fix is easy.

The fix involves deleting some keys from the registry.

Run regedit (Start>Run>type regedit in the open box and click OK)


Delete the subkeys HardwareID and Store

Try this Citrix connection again. This time it should pass Negotiating Capabilities and work.

You might also want to change the permissions on the MSLicensing key. Users and Power Users should have Full Control permissions to it and all subkeys.

Hi Toby
Do you delete these from the client registry or the server registry?

I'm not sure exactly on your setup. You may want to have a look at this document in case anything else is relevant to your situation:

Also, sometimes a situation arises due to TLS/SSL. I've found if SSL 3
is enabled in IE Advanced Security settings, connections will fail. But that usually give a different error message so probably will not apply. That's about all I know.
