Authentication Issue

Question

Hello All 

 

I had deployed my class asp code in IIS in the new server same as setting I had configured into the new server same as existing, but here when I am trying to access it asking domain name explicitly instead of username and password, but in existing behaviour, without entering domain name I am able to access. This is basic authentication type configured in IIS both existing, new servers

 

kindly help me is there any other setting  I need to do anywhere in IIS to resolve this issue.

 

Regards

Anand
