Server 20003 keeps droping internet

[legion1202]

So.. I have about 40 clients connecting to my server 2003 in my office. We have 2 other remote office so those clients connect by RDP. We have been having a strange issue where users loose connection out side the office but the people in the office say connected. The people that stay connected however can not reach Google or use outlook. When this happens I have to restart the server and then everything works fine. When the internet seems to go down we still can print (in office) and I can ping the server, workstations etc. I however cant ping my sonic wall or my gateway. My isp and I have had runarounds and they swear it is not them. They keep telling me we have not lost connection with them in over 14 days.

I do however want to learn towards a broken nic card or a messed up DNS. When I do nslookup it gives me a time out error and says

cant find server name for address 107.7.59.210

Default server:unknown 107.7.59.210..

I did not set this server up. The lady who did is no long with the company.. Can someone give me some help please ..

[medic1202]

i`m starting to think this might be a sonic wall issue. I have two tz 170's and one tz100.

The server is behind a tz170. When the internet net goes out the mains offince local internet still works. We can print,scan,etc.. I can ping all the workstations and switches but I can ping my sonic wall or my gateway. Any thoghts??

 

[Emerald]

are there any logs you can look at first in the Sonicwall to see if it is traffic related like DDoS attack or a virus from the inside flooding the network.

the other thing is that people say that it could get hot and to make sure it is in a cool well ventilated location.

otherwise I am also leaning towards an issue with the Sonicwall.

 

[medic1202]

I doubt it is a virus attack.. Problem is we cant get into the sonic wall. We are a medicare agency and the sonic wall is run by a seperate company do to HIPPA terms and crap. We never had this problem when the same company ran our servers. I think the problem is the sonic wall cant handle all the outgoing and incomming. It was fine when it just had to hand the outgoing but we have like 7 diffrent offices accessing the the server behind the sonic wall. My next step before replacing the stupid thing would be to use the two network cards on the server as followed.


Network card A. Goes behind the sonic wall and only people that deal with medicare access that way..

Network Card B. Just goes through a normal switch/router(use for all personal trying to connect to the server.

Maybe this will take off some heat on the sonic wall..

Anyone have any better ideas... ??

 

[Emerald]

that might be a solution.

the other question what type of internet connection do you have in place? up- and download speed?

 

[medic1202]

we have a T1 2.6 down 2.8 up... Wow my comcast is faster at home =(

 

[medic1202]

the t1 is also bonded

 

[Emerald]

that should be enough bandwidth to handle the traffic

 

[medic1202]

Thats what i think. SO what do u think the best solution would be? Divided the network? I have 1 gate way, a server, and then the soncic wall which acts as the internet way at 192.168.52.1.

My server has two nic cards. I have 5 users the need to use the sonic wall to get into medicare. is there a a way to route those people to use a ip address that goes behind the sonic wall and then have my other users use a diffrent ip to log into the server? Would the stop the sonic wal lfrom over heating?
