Sometimes it is the case when your SharePoint server keeps on prompting for credentials. After some amount of googling and going through some reliable blogs I found following solution. Open Run Type “regedit”. In the registry window left panel find HKEY_LOCAL_MACHINE > SYSTEM > CurrentControlSet > Control > LSA Now right click LSA and select New > DWORD. Now Rename DWORD to "DisableLoopbackCheck". Set its value to 1 and Select Hexa Decimal. 6. Click OK. That’s it this will disable loopback credentials prompting. Regards, Keyur Pandya
