After connecting through our VPN software (MUVPN by Watchguard - V7.3) remotely, users are experiencing slow logon times when returning to the office. After entering network credentials, the logon box hangs at 'Applying Computer Settings' for around 10-15 minutes. MUVPN deploys a 'deterministic network enhancer' which has a patch available to supposedly fix this issue (http://www.deterministicnetworks.com/downloads/dneupdate.asp
). However, I have just tried to connect to the domain on a laptop with this patch installed and still we are experiencing latency when applying computer settings.
All clients are running fully patched XP SP2, with both wired and wireless access to the corporate LAN.
I've just discovered that stopping, then disabling the NLA service & rebooting resolves the latency issue - However, this isn't a particularly nice fix as the users in question are constantly connecting to various networks to establish their internet connection - and Microsoft insist that this service is a necessity for the smooth running of such changes. (As well as optimising GPO deployment).
Has anyone out there experienced similar issues? If so, what fixes have you applied? Is the disabling of the NLA service the only way we can overcome the latency?
