Slow internet connection for a group of users but not all users
My office consists of two companies, Company A and Company B.
Company A is a windows domain enviroment, with 4 workstations in one room. A DLink Gigabyte 5 port switch is used in this room for network connections.
Company B is a non networked enviroment and basically just use the internet.
I have a watchguard firebox X for a firewall. I also use its ports as a switch for everyone. My windows sbs2003 server handles dhcp for everyone. In the past week, Company A's internet connection has been amazing slow, while Company B is doing fine.
I orginally thought the Dlink Gigabyte 5 port switch was the culprit and replaced it. Did not do anything. I have also noticed that early morning at later afternoon, the internet gets much betterfor comapny A. Again, company B is having no problems at all.
What could be causing this.
Thanks,
Craig Bayer

I'm guessing that company A is using the server for DNS. Your DNS is probably hosed up. Reboot your server and it will probably fix it. Or just stop and restart DNS on your server. You are probably having timeouts waiting on DNS and then going to the backup DNS which is proably your ISP's Company B not being in your windows group is probably just using the ISP and therefore not having to wait on timeouts.
Also if you only have 4 computers, you could put in entries for your windows domain and server into an HOSTS file on each machine and then point them to the ISP's DNS like company B and work if you can't get the DNS resolved.. if that is your problem, but a reboot of your server should be it. If that doesnt' fix it you might also be having a probme with your server's DNS being setup wrong and it may need to be setup right if it is setup to 'forward' requests instead of looking them up on it's own.. but it really depends on how everything is setup- this is just a best guess without knowing how everything is setup for TCP/IP based on what you have said.

All companies are using the Server for DHCP. Company A is directly connecteted to the Firebox X while company B is connected to a DLINK DGS 1005D So, I am going to restart the server. If that does not fix it. I need to check my DNS settings on the server. Let me try it out.
ASKER
Restarting the server and stopping and restarting the DNS have done nothing. ANy other ideals?
its a switching issue probably.
switch some users from the dlink with some on company A> it should not make a difference.

and what model we dealing with.
you useing a x-over cable?

I am not usre about the dlink switch model, I am out of the office, but I have already replaced it. I am not using a cross over cable but a regular cat 5. Could that be the problem
i meant what Watchguard product. x5? x500? edge?
and it depends on the units.. if they have autoswitching it "should" work with either cable.
Older switches/hubs had a internal crossover port that would do the same trick.
Does the port the switch is plugged into have a link light?

Firebox Edge and yes to the link light
play with cables... I had same problem in a remote office, those cheapy switches dont seem to get along very well..
i did solve it by playing with cableing. I think i used a cross over, but i dont remember.
try and find the model of the dlink too.

The Dlink Model is DGS 1005D. This problem seemed to go away for a little last week and now its back. I am going to replace all the cables, but could it be anything else?
not even necasairly replace the calbes... maybe the one doing the uplink is where i would start.
i read the manual, its auto negotiating on any port. so you do not need a cross over.

Maybe this is your issue?

The base model Firebox X Edge includes a 10-seat license. This license allows a maximum of ten devices on the trusted network to connect to the Internet at the same time. There can be more than ten devices on the trusted network, but the Firebox X Edge only allows ten Internet connections. A seat is in use when a device connects to the Internet and is free when the Firebox reboots.

The other company only has 4 computer and we have 4 so that would be 8. I will check the uplinl cable
networked printer that are trying to broadcast could count to maybe? not sure.
ASKER
No network printers, only shared. I replaced all the cables this week and it seemed to maybe get a little better but still happens.

Thanks Jay, Lawot please post any updates, its nice to add any information to this site to help others.
is company A directly connected to the FB unit? while B is via the dlink?
SO all companies use the same DHCP server, therefore same DNS and same ip subnet?
