Could the problem be caused by a computer attempting to connect to the server while it's already at it's max lan connections?No. On picture you gave - host can't establish network connection with router, I usually see this when dhcp server is down, or with wireless connection problems. If there are problems in network beside other host connect to server (like internet is slow or non working) check switches for redundant links. If you have more than one link between switches and STP is not running on switches than network loop occurs, and network goes wild. In most cases it is easy to check for network loop - all lights (connected ports) on switches are light up (not blinking) all the time.

As I suspected, that Cisco RV220W really wants you to leave DHCP enabled for everybody and then use their "Static DHCP" section to assign ip addresses you want constant.
What happens is that Windoze never goes through DHCP negotiation if it is set to a static ip locally and, as a result, never identifies the network (which is a problem found all over the web)
Your manual: http://www.cisco.com/c/dam/en/us/td/docs/routers/csbr/rv220w/administration/guide/rv220w_ag_78-19743.pdf
I like to reserve .100, .101, etc. for servers and .151, .152, etc. for network printers with all of the clients set to use automatic DHCP.
If the server is on more than the other PC's, check out adding the IsDomainMaster to its registry.

Yes; the computer browser service looks for the PC which will maintain the list of PC's on the network and that setting makes it be the top dog.
I've realized that not all computers are setup the same, which is something I'm going to have to change. Some request a static IP while others obtain automatically.I believe there is no need for that. You just need to configure DHCP server to assign IP addresses from IP address range not to overlap with your static IP addresses. You can assign dynamically addresses from some IP range for example 192.168.x.51 - 192.168.x.250 (DHCP address pool) and use IP addresses 192.168.x.1 - 192.168.x.50 & 192.168.x.251 - 192.168.x.254 for static.

I agree, but this is IT and always something is changing ( "that's the way I like it").

Well, if you have a lot of hosts it is hard to configure all devices manually. Otherwise static is preferred - if DHCP server is down your local network will still be functional. As network starts to grow you need to have spreadsheet (or whatever method you like to use) for tracking static IP assigns so there would be no duplicated IP addresses... Benefit of combination static and dynamic IP address assignment is that you just configure essential devices with static IP addresses (servers, printers, routers etc) and rest of devices get address from pool since usually it is not important what is IP address of those devices.

What type of switch?The main router is a Cisco RV220W. The wireless is turned off and isn't used.
ASKER
I guess you didn't catch my last sentence... Setting the router to reserve the ip's (Cisco calls them static ip's) of the devices (PC's, Servers, NVR, printers,...) in the router made everything happy AND I did not have to change the ip settings in the devices; I left them with the ip's I had already set previously.
All of the network devices which don't need to be shared or remotely accessed, I left using DHCP which was their default, anyway.

Suddenly, I think we are working on two problems with the primary one posted not being what needs fixing.......
Windows has several session timeout parameters that cause "inactive" network connections to be disconnected. In most cases, the default is 15 minutes of inactivity.
Here are some settings to fix it: http://www.nextofwindows.com/how-to-fix-the-red-x-on-the-icon-of-mapped-network-drives-in-windows-7
And/or, here's a different spin. I have named my server ECCxx for almost 20 years now where the xx is the year I put it in service. Suddenly, about 6 years ago, none of the workstations could wake up the server to access the shares. When I checked with Pingplotter (a great free visual traceroute), I found to my chagrin that EarthLink had decided to search the world for my server causing all sorts of grief. The permanent fix is to add an entry to the LMHOSTS file for the server which I have now used on hundreds of peer to peer networks with great success.

"if you go to the server and 'move the mouse', it instantly fixes the problem" sounds like a Power Saving option. Make sure the server does not go into any such mode, switches off devices etc.

Try setting a screensaver (Mystify and 10 minutes, maybe?) and telling it to never dim or turn off the display. My thought is that maybe its hanging on some portion of doing those.
Is hibernation turned off as well as sleep?
If not - cmd as admin
powercfg -h off

OK; that's a very old ATI Radeon 7000 video card and it doesn't meet the specs for DirectX in 7.
But; your post has me concerned about what other drivers were not installed so, what is the make and model of that PC?
Try not turning off or dimming the display without a screensaver.

Apparently, that ATI card is actually an ES1000 built-in on the systemboard.
The support page does not list 7 as a supported O/S; but drivers for Server 2008 will work. Normally, chipset, network, and video drivers are always needed:

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.

I noticed that on update, the network mapping drops every 15 minutes or so depending on the update cycle set.
Changing it to Update or Create should fix that if this is the case
As for the limited connection, sometimes the server can try and finish that test before some services are loaded. I often find that I need to restart Network Location Awareness (Dependent on Network List) to get it showing proper. There is no outage from restarting that service on the server.
