Hi all (my first post here).

I have a weird problem with WLM. I've searched for a solution but many boards (including this one) do not allow searches on words < 4 letters, and my problem is with a VPN!

I can connect and use WLM quite happily, no issues. I can connect to a VPN quite happily, and continue to use WLM and the VPN quite happily.

BUT if I then log out of WLM, either through a connection glitch or because I need to change username, then I can never log back in to WLM unless I disconnect from the VPN first. All attempts to login result in error 8100030d.
