Can it be due firewall issue or anything I can check on server

Use
slmgr.vbs /dlv

To check the registration details. You should find kms name then
Test-NetConnection -computername <kms server> Port 1688 InformationLevel Detailed

From you server where the error is.
If successful the server can reach your kms.

Can't test the command right now so syntax may be imprecise

Where do I find KMS server name
0
pramod1Author Commented:
It says test-net connection-computername not recognized

MichelangeloConsultantCommented:
typing
slmgr.vbs /dlv
should show wether the client is referencing a KMS host or not :look for KMS REGISTERED MACHINE NAME: servername:1688
to use KMS.. the client needs to be using KMS licensing.. so the key you enter on install should be a KMS key, and not a MAK key.

If you have a select contract type you can use a Kms and install KMS keys: here is a list

Is the server not able to contact kms host or license is not installed?
