New Server on Lan

I've recently added a new sbs 2011 server to a local customer.  The migration went fine, save for an issue with time matter which has become a non issue.  The customer is having ongoing slow log on issues since the switch over.  All dns information is correct on both the server and the client pcs.  I've flushed the dns on the client machines.  They have to wait roughly a minute and a half to log on after booting the machines.  The logs show userenv authentication issues, and a couple of group policy errors.  This is a very small shop, truthfully only got an sbs server because they insisted.  No group policies in place.  Active directory is barely used, and no exchange.  Any thoughts?

You say DNS is correct but 90% of the time slow logons are caused by clients pointing to an alternate for DNS.  Their NIC configuration must point ONLY to the SBS, if  router or ISP is added, even as an alternate, you will have slow logons.  Might that be the case?

I am assuming this is SBS standard and not SBS Essentials ??  The same applies or Essentials, but there may be other places to look as well.

No group policies in place.

By default, SBS 2011 has about 10 group policies -- so I would suspect you do have some.  One of them could be responsible -- but don't go messing with the Group Policies because the default ones are all managed from within the SBS Management Console.

If you've enabled Folder Redirection for users then it would be very common for them to have slow logons for the first few times if their files were previously stored on their workstations.  

Also, you mention that you migrated to this server... so were there any login scripts on the old server?  If so, those should really be replaced with Group Policy Preferences -- plus there could be something in the old logon script that doesn't exist anymore which would cause a delay in logging on.

If none of those, then I'd suggest you post a COMPLETE IPCONFIG /ALL from both the server and a workstation.

Affirmative on the sbs standard.  All workstation dns is pointing at the new server and the new server only.  No login scripts.  You are of course correct about GP, I meant no custom policies had been enacted.  My bad. No roaming profiles.  I'll get the ipconfig /all, good suggestions thanks.

I didn't ask about roaming profiles.  My question was about Folder Redirection -- which only redirects specific folders, usually My Documents by default.

This is enabled on the server by default with SBS 2011 -- look at the Server Management Console > Users , and then check the properties of any user.

I generally recommend that you let your SBS handle DHCP.  This way you are sure to push out the proper settings to your workstations.  That aside, you MUST remove the 8.8.8.8 DNS server from your SBS's configuration.

If you want to add an external DNS Server you can do that as a FORWARDER on the DNS server settings.

After removing it from the NIC config please run the FIX MY NETWORK wizard.

So I agree with your advice regarding the DHCP, and I decided to install that role.  Got to the point of validating the dns settings and got the error message that the dns server is not available.  This is the dns server.  The dns service is running.dns validation failure for dhcp role installation

If you are going to configure DHCP on your SBS you first need to disable the DHCP Server on your router.  Because otherwise the SBS will detect it and won't move forward.

Then, once you reinstall the DHCP Service, just run the Fix My Network Wizard and it should configure it for you.

Unfortunately DHCP needs to stay on the router to be able to supply ip addresses to a small sub-office.  And the router does not allow for setting up separate vlans.  Unable to get dns server recognized, nslookup does not find it.

I assume then that everything is on one subnet?

Though it is definitely preferred for many reasons, the SBS does not have to be the DHCP server, however whatever you use for a DHCP server MUST hand out ONLY the SBS server's IP for DNS, and must provide the domain suffix. It cannot provide the router or an ISP for DNS, even as an alternate.  Thus if that is the case, why can you not use the SBS as the DHCP server and allow it to assign addressing to the "sub-office" as well. There is no difference in the security risk.  Also SBS offers filtering by vendor class ID's or reservations such that you could assign different parameters, such as DNS, to the "sub-office" clients.

Alternatively using even inexpensive routers you can isolate the sub-office for security and allow them their own subnet and DHCP server.

Apologies for the lag.  Customer has opted to replace time matters with another product, so the old server will be out of the picture.  Will recheck dns settings at earliest opportunity.

The technician that installed this server created a new domain with the same name of the old domain instead of joining the SBS server to the domain or joining the other server to the new SBS domain. The old server has been eliminated from the network and everything is running fine now.

This was an oversight by the tech that installed the server and posted this question.
