  • query on DNSlint result

    I need a clarification on DNSlint result which i perpromed on my DC and ADC. I have only one DNS server (172.16.51.196) and I ran dnslint /ad 172.16.51.76 /s 172.16.51.196 command on my DC and ADC and faced two different resluts. Please see below.
    1. Report from ADC
    dnslint /ad 172.16.51.76 /s 172.16.51.196

    Total number of glue (A) records this server could not find: 1
    Glue (A) records are missing for the following CNAME records:
    eric-pdc.ERICDOM
    I have replication issues with my DCs and ran the above command to verify/confirm whether DNS is playing any role in this.
    Please help me in clarify why i got two different results for a same query. Are ther any issues with DC. Are there any role of glue A recore in replication. If so how to manually vreate it...
    Thanks,

    Re: query on DNSlint result

    What type of DNS zones have you got configured?
    For replication info check the Replmon tool from the Res kit.
    May I ask if there is a reason you call your domain controllers with that naming convention? ADC, PDC etc. AD is a flexible environment and FSMO roles in a Domain Controller may change if ever there is a need.

      Thanks for the reply...

      I have two primary zones created in my DNS (but not AD integrated).
      One is _msdcs.ERICDOM
      Another is ERICDOM (note: ERICDOM is my domain name)
      I can see all the required host files and SRV records in DNS. But one thing I want to clearly mention here. Sometime back ForestDNSZones and DomainDNSZones were deleted from DNS. I am not able to restore them. Except these two directory partitions, I have everything fine in DNS. Can you please guide me whether is there any procedure to restore deleted partitions.
      I have verified through ADSIedit.msc, but I didn't find these partitions. But when i try to create default application partition from DNS console, I am getting error "data is invalid" and not able to create.

      Thanks,
      Raju P.
