| Hi all;
How can I determine the MTU of a NIC in Windows Server 2003 and Windows Server 2008?
Thanks

| Hi Reza
Is it an Ethernet connection? If so, it should be 1514. However, bear in mind that if you are using VLANs with frame tagging from the NIC itself [not recommended] it will burst this size. However, the receiving switch will strip out the VLAN Tag to bring it back down to 1514.
This URL is a great resource for finding the default MTUs for different layer 2 connectivity technologies:
http://support.microsoft.com/kb/314496
Also, go to the advanced properties of the adapter and look at the Jumbo Size properties. Here you can increase the MTU.
Alternatively, here is a VBS that will do it for you (doesn't work on 2008 though):
http://gallery.technet.microsoft.com/ScriptCenter/en-us/49c26363-d46c-4288-9c8d-feb0a1982998
Stone in the bush - are you having repl issues because of the MTU? Recently installed SP2 on 2003? Let me know because this is a known issue.
Regards,
Rob

I use Ethernet interfaces and just want to know that which value is configured for the MTU field of a interface...

| Download scriptomatic from the technet script center and then use it to
generate a script that shows the usage of the
Win32_NetworkAdapterConfiguration class . (Sounds harder than it really
is - you just have to select this class from the drop down and the
script is generated automatically).
This will dump out the MTU and a lot more settings that you want !
