Post subject: Problem DNS Server

Greetings Karl or Alan

At the moment I have problems with the DNS Server. Continuation I show my present configuration to them.




INTERNET







ISA SERVER 2004





DHCP/DNS SERVER



FIRSTSPOT (192.168.1.0)





(192.168.1.7)



SWITCH MANAGED





AP



AP



AP



CLIENT



CLIENT



CLIENT





Until this point everything works very well

But every certain time (day) the clients cannot sail in Internet

The configuration of present network of the client is the following one:



IP

192.168.1.XXX

MASK

255.255.255.0

GATEWAY

192.168.1.1

DNS1

192.168.1.7

DNS2

0.0.0.0

DHCP SERVER

192.168.1.7

We have a DHCP /DNS Server based on Windows 2003 Server Enterprise. and direction IP is: 192.168.1.7

With this configuration the client must sail in Internet, but the clients do not enter Internet. The Internet Explorer says that there is problem with the DNS. We have made the following steps:

Reset DHCP/DNS Server

Resetear AP

IPCONFIG /FLUSHDNS

IPCONFIG /REGISTERDNS

NSLOOKUP

TRACERT

PING IP (FIRSTSPOT, DHCP/DNS, ISA SERVER, ETC).







But with no of these actions the client can enter Internet. The Internet Explorer continues saying that there are problems with the DNS.

But if we make RESET to the FIRSTSPOT SERVER. The FirstSpot begins To work and the Client begins to enter Internet







My question is: That it can cause DNS problems? and because the FirstSpot lets work?

I remember to you that we have placed as DNS Server the FirstSpot and happens the same. The present version of FirstSpot is the 3,14 and this working in Windows 2000 Advanced Server.



I wait for a quick answer. This problem every month happens each 8 to 20 days. and we cannot have UPTIME the FIRSTSPOT Server by but time without we make RESET to the FIRSTSPOT SERVER







Sincerely

Ali Vivas / Darwin Vivas
