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.
