Mapped drives on server 08

Hi Folks - I just setup a new Server 08 in my existing domain. After adta transfer I mapped drives to all 107 stations. All works for about 2 hours. Then users can no longer save to mapped drive. In about 3 hours they freeze when trying to access mapped drives. Any ideas?
Thanks in advance, Pat

Any AV software running on the file server? what message do the clients get? how have you been resolving the issue?

PFSullivanAuthor Commented:
Thanks for the reply - No AV software running yet - The server is only up for 2 days - have reboted every few hours.

when this problem happens are you able to browse to the shares from clients or the server?

Has Powershell sent you back into the Stone Age?

If managing Active Directory using Windows Powershell® is making you feel like you stepped back in time, you are not alone.  For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why.

I can browse to everything on either server - but the workstations can only browse intermittantly or it takes 5 minutes for a folder view to open or (if it opens) save

Mike ThomasConsultantCommented:
I wonder if you have a networkbottlneck? is anything different between the server/client connections why can you still browse OK and they cannnot?

Only changes made in the last week were - New 08 server, remap all workstation drives to new server, and a 1Gb Switch - All worked well until introduction of the new server - I still have the 03 server handling DHCP.  Erro log shows an occasional DNS error - I am using Opendns.org for DNS resolutions.

This is the only warning I receive in the event viewer -

Task Category: None
Level:         Warning
Keywords:      Classic

Description:
The DNS server is waiting for Active Directory Domain Services (AD DS)
to signal that the initial synchronization of the directory has been completed.
The DNS server service cannot start until the initial synchronization is complete because
 critical DNS data might not yet be replicated onto this domain controller.
 If events in the AD DS event log indicate that there is a problem with DNS name resolution,
 consider adding the IP address of another DNS server for this domain to the DNS server
 list in the Internet Protocol properties of this computer.
 This event will be logged every two minutes until AD DS has signaled that the initial
synchronization has successfully completed.

How long ago did you build the dc and how many dc's do you have?

Run dcdiag /test:dns and see if everything is ok while your waiting on replication.

I see 2 nics, they appear to be on different networks I will look at this closer when I get back to my pc. But multihomed dc's can cause issues and are not supported by MS iirc.

By the way - This server has 2 Intel 1000 NICS on board - They are structured for load balancing

Mike ThomasConsultantCommented:
Ok teaming us not supported either, set them to a standard config just for testing or better off remove and team or load balance and disable one. The only real way to get teaming to work is using failover but it still results in some issues and can cause dcdiag to fail so best to rule that out.

OK Mojo - I disabled one card as you suggested - I also changed the DNS server on the 08 to the IP of the 2003 server as that one passed the DCDIAG test.
There is no improvement yet so if you have any ideas, I'm all ears.
Thanks, Pat

Great stuff, so long as the clients can still connect using this config I would be inclined to leave things as they currently stand and see if the clients still have an issue or hopefully not.

If this resolves the issue with the clients then we just need to tackle your original config, what to do with it and the reasoning for it etc...find another way to deal with it.

Either way though a problem has been solved, just maybe not the one you had in mind when your originally posted, but my gut tells me its related, probably to the nic config rather than dns being upset as a result of that config though. ;)

Ack, just read your post again? so the clients are still loosing connectivty to this server after a few hours?

Are there any clues in the client event logs?

Ok try this.

Next time this problem occurs rather than reboot the server discconect half the clients from the shares (when you reboot the sessions are being ended anway) see if you can prove it is to do with the number of client sessions.

(To do the above you need the file server role installed then you can view the file shares and the sessions for each share like you could with 2003)

If disconnecting half the clients allows other clients to connect ok run performance monitor with the defaults and see if you can identify a bottleneck.

Hi All - Thanks for the input from all fronts

In the final solution - The server had been loaded with win08 64 bit - All my stations are XP

It was mojotech who got me on the right track. I reloaded the OS on 32 bit and problems disappeared.

Both servers are now working perfectly in tandem.

FYI - There was never an event logged on servers or stations - I think MS has a small conflict problem here - My goal was to prepare for the Win07 platform.

I would like to award the points to Mojotech.

Thank you all again for your assistance.

regards, Pat
