Router DHCP services do not support many of the functions that Windows DHCP supports regarding DNS registration, WINS settings including Hybrid node type, and basically Option 081. I highly recommend disabling the router's DHCP service and use your Windows server DHCP and set the following options: > > 003 192.168.1.1 > 006 192.168.1.10 > 015 EPMapleGrove.local > 044 192.168.1.10 (this is the WINS server) > 046 0x8 (this is the WINS node type) > > As for the fowarders you have listed, jot the list down on paper, then remove them, and try the following: > 4.2.2.2 > 4.2.2.3 > > Then flush the DNS cache.

This will also tell you if the response goes thru as TCP and not UDP. Try an nslookup for Yahoo's MX records before you make the changes and you can see how large the response is.

If it works with the vc switch, and not without it, then it is an EDNS0 block. I provided hotmail.com as an example because it's response is definitely greater than 512 bytes. You can also not set it to 'mx' and leave it default when you invoke nslookup, and then try aol.com, microsoft.com, yahoo.com, as some examples with large responses. > > > Ace > > > . >
From: kj [SBS MVP] on 9 Mar 2010 12:14 Jumping in late and not seeing which verison of SBS is in play. This configuration is automatically ( and correctly ) done for you in SBS by using the built in wizards (CIEW). EDNSO support is a different matter, but configuration of SBS should be done with the wizard and verified with the Best Practices Analyzer. This will allow you to focus troubelshooting to the external devices.

From: Terry on 11 Mar 2010 13:21 First I want to thank everyone that replied to this post. I tried all the suggestions even the Best Practices Analyzer, nothing helped. So I bit the bullet and called Microsoft. After 5 hours of the MS tech logged on to the server and one of the workstations he came to the figured it was the Norton (even though it was turned off)! We uninstalled Norton I experienced no problems after that. Again Thanks "Ace Fekay [MVP-DS, MCT]" wrote: > "kj [SBS MVP]" <KevinJ.SBS(a)SPAMFREE.gmail.com> wrote in message news:%23t2DFw6vKHA.3896(a)TK2MSFTNGP02.phx.gbl... > > Jumping in late and not seeing which verison of SBS is in play.

Even when disabled, they affect functionality until uninstalled. Thank you for updating us and letting us know what the problem was and the fix. Ace |
