Issue while configuring MobileClient

Hi Friends,

I am configuring MobileClient and followed the relevant step associated to it. After creating the service, I am getting below error.

Server instance: MobileClientIndia
The service could not remove service principal names because the service account could not be found in Active Directory.
Account: ad\IXXXX-NAV01$
Service principal names:
DynamicsNAV/IXXX-NAV01:20046
DynamicsNAV/IXXX-NAV01.ad.agi:20046

Could anyone please let me know how to solve this issue?

Thanks in advance.
