Recently took over a network that was mismanaged, neglected, and run by an monkey. I'm NO genius; Maybe an ape... But I'm smart enough to know there was a LOT of things neglected with the network. Anyways, onto an issue I currently face. Users are having issues with web browsing. A few times a day users will see "not connected" in their web browsers. This is about 100 people over multiple sites. It lasts for a few seconds or up to 2 minutes. Signal strength and wired connections remain connected. The exchange server always works and staff can still send/receive while the browsers are down. It's all users but not at the same time. It happens to everyone intermittently but never company wide. On the local machines staff get the warning: "The device or resource 'www.google.ca' is not setup to accept connections on port ...HTTP". So I assume it's a DNS issue. There are two DNS servers in the company. One on the AD server, and one on the Exchange server. When I check event viewer, there doesn't seem to be any issues. When I google the error that the users get, I see people advise to 'update windows'. Here's a beautiful issue: WSUS was configured on the AD/DNS server but hadn't properly run in years. And where it HAD been setup, users can not manually install updates. So there are a lot of staff here with dated/non-updated machines. I removed WSUS as a role on the server last week and I've been testing local machines and they still seem to be waiting for WSUS (and won't update) so I might add it again as a role and configure it from scratch (which is something I'll have to do for everything over the next year). I doubt it's routers and switches but I'm not sure. I need a heads up from some sys admins to give me an idea where to start poking my head around, or maybe someone has faced this before? Thanks!
