Invalid name:appropriate prefix not found; choose another name for another server

Hi,

I am using nwds 7.3, while doing changes in already existing DC I am not facing any issues. But when I create a new DC, and application is created it throws a warning nvalid name:appropriate prefix not found; choose another name for another server. I have checked th SLD the name is being reserved and exist there. Though I checkin the code but gave me same warning message and the transport got stuck in CMC.

Please provide a solution for this.

I have gone through the thread but no use
