Can you run dcdiag on each DC in turn please? What are the results - anything untoward?
All the dc's are in the right areas within sites & services?
No registry changes forcing clients to use a particular DC for logon?

I want also to inform you that I demote all servers before and reinstall windows again to insure it is clean
Also make sure all DNS records and sites and services not contains any data about demoted servers also check fom NTDSUTIL metadata and then I promote them again
but still has the same problem
I solved the problem by adding all authenticated users and everyone access computer from network at default domain controllers GPO .

Thanks everybody

Ahmed,
I'm not sure exactly what will solve the problem, but here's where I would start:
1. Make sure that you've configured your sites correctly:
- You've created subnet objects for each IP subnet
- You've assigned each subnet object to the appropriate site
2. Make sure that each server is in the correct site
- Keep in mind that domain controllers do not automatically assign themselves to sites the way member servers and clients do.
3. Make sure at least one DC in each site is a global catalog server
4. Make sure you've got two DNS servers in each site
5. Check your event logs for any of the following errors and warnings:
- DNS
- NTFRS
- Kerberos
- Active Directory
I know you mention that all DCs are GC, time servers, etc. Regarding time servers, your PDC emulator should be configured to sync to an outside time source and all other servers and clients should be left alone.
What are your thoughts?
