So we have been having this issue at work and I can't seem to nail down a fix, short of manually editing the registry which is cumbersome and a pain.
We have file server A named XXX-XXX-File01 (Windows 2003) and we're replacing them with file server B named XXX-XXX-FILE81 (Windows 2008 R2). What seems to be happening is that on all laptops and desktops when users try to open an attachment or file saved on the :L: or H: drives it looks for the old server first them times out and looks for the new server, this causes a lag and complaining from the users.
The L: drive is their local drive for users to share locally and the H: drive is their home drive that only they have access to.
Right now what I have done to resolve it is edit the registry and anywhere there is FILE01 I'm changing it to FILE81, but there HAS to be a better easier way.
What am I missing? Hope the post is clear enough.
