Hi ,
1.Make sure you add 'Microsoft KM-TEST Loopback Adapter' via device manager.
2.Uncheck everything except Internet Protocol Version 4 (TCP/IPv4):
- Disable 'Client for Microsoft Networks'
- Disable 'File and Printer Sharing for Microsoft Networks'
- Disable 'Internet Protocol Version 6 (TCP/IPv6)'
- Configure 'Internet Protocol Version 4 (TCP/IPv4)'
Should as picture below:
3.Open up the TCP/IP v4 properties of that NIC:
- Set IP address to match the VIP on the load balancer
- Set subnet mask to 255.255.255.255
- Leave default gateway blank
- Leave DNS servers blank
- Disable 'Automatic Metric' and manually set to 254 on the IP Settings tab.
- Disable the 'Register this connection's address in DNS' option on the DNS tab
- Select 'Disable NetBIOS over TCP/IP' on the WINS tab
Warning: If the server is running the Microsoft DNS server (including if it is a domain controller) you must edit the DNS server configuration to only listen on selected IP addresses. If the DNS server listens on the IP addresses that belong to the loopback adapter it will continue to register itself in DNS.
Also , try to disable DNS registration via PowerShell to do a test, see if it works: Get-NetAdapter loopback_name | Set-DNSClient –RegisterThisConnectionsAddress $False
If all above steps still didn't work, we need to trace network traffic to find the cause. However, analysis of network traffic is beyond our forum support level and due to forum security policy, we have no such channel to collect user log information. So we recommend you open a case with MS Professional tech support service, they will help you open a phone or email case to Microsoft, so that you would get a technical support on a one-to-one basis while ensuring private information.
