Why does windows take a long time to load with a roaming profile?

Question

Active Directory

Good afternoon colleagues.
We have a domain and a number of users with roaming profiles.
Recently there was a need to transfer user profiles to another server, as the old one fell into disrepair.
Transferred in haste using robocopy. Raised a new server based on Windows 2012, created a ball, gave rights.
In the domain policy, the paths to the new server have been changed.
Now every day we see users have a long computer load. On the screen there is an inscription: "Welcome", the user's session is visible on the server and that he opens all the files in the profile for "reading" one by one.
Loading time can take an hour... which is very long.
The server was checked. Memory - a shaft, the processors are idle. Disks are idle. In the properties of the balls - caching is enabled.
Give advice what else to see until our IT department is executed?
I'm *NIX-oid myself, but I'll get it too.
Save your friends!

Answer 1

I was helped by changing the server name from short to full in the profile settings for AD accounts, it was
\\srv\userprofiles\username
made
\\srv.domen\userprofiles\username

Answer 3

At one time, it helped to prescribe the correct DNS servers corresponding to the domain controller on client computers.
AD uses DNS for its own purposes.
