DNS Not working. Please Help!!! RRS feed

  • Question

  • Hi,

    I am having a problem with my network. This is a network that 3 servers (2 are remote). The problem is that I have 2 computers that say they are connected to the network (ie, My computer properties say that it is part of a domain) but are not seeing 1 of the servers that a program on these computers use quite frequently. The only way for me to make the computer see the server is to go to the command prompt and use "net use and the server name" and put in the admin credentials. I have already checked the permissions of the user and they are literally the same as the admin. I have tried to rejoin the domain but it tells me that the DNS is not available. 

    Any help that anyone can provide would be greatly appreciated. I hope that I have provided enough details. If you need clarification, please ask and I will do my best to clarify.

    Please note that there is a firewall (IPCOP) at each location. Just providing this info in case it may be a part of the solution.

  • Hi Katrinj1,

    Are you able to do a nslookup from host A to host B internally ?

    Possible to use ip address instead of host name ? if ip address works, then high chance it might be a host file issues.

    Try it this way net use z: \\xxx.xxx.xx.x\abcfolder

    click start run > type drivers > go to etc > open up host with notepad.

    add the ip address & the FQDN of the host > then save host file.

    (FQDN) = fully qualified domain name --> e.g host.abc.com

    Let me know if any of the above works. I will be glad to assist you further.

  • What do you mean when you say do a nslookup from A to B? All I know about nslookup is typing nslookup at the command prompt.
