DNS issue

Hello,

I work in a school district and we frequently goto a websites hosted locally at our DA site.  Even though the websites have a 10.* IP, I have to constantly clear the cache off our DNS server and run ipconfig /flushdns, then ipconfig /flushdns OR restart the client computer before I can successfully log into the website. I can log in if I type the IP address but not through the URL.  Why is this happening?  Other schools do not have an issue logging into this local website.  So I am 100% sure this is a problem on our DNS server or maybe even a route statement in our router.  

Any suggestions?

Thank you,

Ok, the DA Site says the websites sit at the DMZ so I wouldn't be able to PING or TRACERT.

Event Type:      Error
Event Source:      DNS
Event Category:      None
Event ID:      7063
Date:            5/25/2006
Time:            9:04:30 AM
User:            N/A
Computer:      BRHS-MAIN_SERV
Description:
The DNS server is configured to forward to a non-recursive DNS server at 10.10.10.210.
 
DNS servers in forwarders list MUST be configured to process recursive queries.
Either
  1) fix the forwarder (10.10.10.210) to allow recursion
       - connect to it with DNS Manager
       - bring up server properties
       - open "Advanced" tab
       - uncheck "Disable Recursion"
       - click OK
  OR
  2) remove this forwarder from this servers forwarders list
       - DNS Manager
       - bring up server properties
       - open "Forwarders" tab
       - remove (10.10.10.210) from list of forwarders
       - click OK


This is a reoccurring error in event veiwer.  What all would a NSLOOKUP show me if I run that when the site fails?

Thank you,

Well youre getting that error because the DNS server your forwarding to is unavailable to you. Thats what the problem is. NSLOOKUP will let you query DNS servers for the domain.

I would try both of those corrective actions described in your error log and see if either of them work. If neither of them work; go into your DNS manager and fix the record manually. Find the record for "school-site-thing.com" and edit it to have the proper IP address. Chances are you will have to create this record since your DNS server doesn't seem to know where "school-site-thing.com" is anyway.

When I clear the DNS cache and ipconfig /flushdns, is that the same thing?  Will that clear out the manual record that I created?

Thank you,
