DNS Problems after IP address change

I am currently unable to access any of my internally hosted websites from within my network.

This occured after changing IP addresses.

I can get to them fine from outside of my domain.

Mabye I am missing something simple, but does anyone have any ideas here?

Thanks,

Please explain further.

 

The IP address of my WAN link changed. As a result, I had to make a change in DNS to point my domains, to my Public IP address.

I can access the sites fine from outside of my network, same DNS server.

Boggling my mind for the moment.

 

Two quick checks.

Can you ping the address (not name) that you want to access?

Did you modify DHCP to assign a new DNS address?

DRD

 

Ok, I solved the issue last night.

I have an internal DNS server here which isn't really used much, but is a must have since I am running Active Directory.

I have all clients on my network pulling external DNS server addresses.

I just set my internal DNS server as the primary DNS server and this fixed everything.

It's interesting though, I can go back to using public DNS servers and NO internal DNS servers and hit all my websites with no problem now.

 

I'll bet the logons are quicker now too.

Your Internal DNS needs to know about your Domains.
Alias records need to be created in DNS so he can find local websites.
