Network PCs are taking ages to startup and log in.

Hi

We have Windows 2012 DCs and XP and windows 7
We are having network problems this morning the PCs are not logging in quickly .

When the client  PCs are started it says : Applying computer settings ( takes ages)
and after this it says: Running startup scripts( This also takes ages)
After this I get the login window  and the desktop is completely blank and it takes ages to load the desktop icons.

I saw the events in the event viewer and I saw the below error and not sure if this error is related to this problem.

The DNS server was unable to create a resource record for  74a652ac-fcb0-4253-980d-137942c84944._msdcs.domain.local. in zone domain.local. The Active Directory definition of this resource record is corrupt or contains an invalid DNS name. The event data contains the error.

Logon Name:DNS Server
Source: DNS-server service
Event :4010

Any help to trouble shoot will be really helpful.

Many thanks

Slow logins are usually down to a DNS issue and the error messages confirm this.
Make sure the DNS server is running - maybe restart it. Check that clients are getting the correct DNS server settings from DHCP and that the only DNS servers listed in the DHCP options are your own internal DNS server settings.

This problem has started only today nothing was changed in the past.
I restarted the DNS server service on the DC. The clients  are getting the right DNS settings when I do IP Config.

On the client PC I can see running startup scripts taking ages and I get a dos window  and on the dos tab it says C:\windows\system32\xcopy.exe and then goes to the CNTRL+ALT DEL screen

After I login when I open my computer , cant  see any mapped drives.

I then noticed one of our file server was frozen.

One of the drives from this gets mapped to  every user.

After restarting the file server logins were working as normal.
