DescriptionThe zone zone name failed zone refresh check. Invalid response from DNS server at TCP/IP address of primary DNS. Check DNS server at TCP/IP address of primary DNS and ensure it is properly authoritative for this zone.
Event InformationCAUSE:
This problem occurs because the zone file on the UNIX DNS server contains non-RFC compliant characters. Some versions of UNIX permit the use of characters that cannot be recognized by a Windows NT DNS name server. 
RESOLUTION:
To resolve this issue, perform the following steps: 
1) Copy the zone file from the primary UNIX DNS server to the %Systemroot%\System32\DNS folder on a test computer running Windows NT that has the Windows NT DNS service installed.
2) Using the name of the zone file, create a primary zone. Click Start, point to Programs, point to Administrative Tools, and then click DNS Manager.
3) Right-click the TCP/IP address of the computer, click New Zone, click Primary, and then click Next.
4) Type the name of the zone file in the Zone name box, press TAB, click Next, and then click Finish.
