Windows 7: Network items getting lost in Explorer/Network menu

Thanks for responding. I never shut off the MediaPC, is always running.

The funny part is an just to mention again, I have a utility that is for the Router, that runs on the main PC that is loosing the display in Explorer, an that shows the MediaPC, an states its active.

You haven't addressed the firewall question :) Which firewall are you using on both machines? Did you try disabling?

(I used to get these error/warnings in Event Viewer on my desktop whenever I started my laptop before I configured firewall to trust the IP of laptop.)

Also, run in cmd "ipconfig -all" on both PCs and paste here please.

Sorry GokAy, don't mean to come off wrong by not having done that, an just want to mention, I know you are trying to help an I greatly appreciate that.

Just to mention, I am very leery in today's age to shutting down my firewalls an only like to do it when I know for sure it's needed.

I guess I could unplug my internet connection for the time, but will have to setup a time for that. As well I have noticed that unless it's from doing restarts sometimes it takes some time for the network system to re-find a item.

So could be kinda, the firewall is off, an then I wait an wait an wait all without knowing if that is issue an its just taking some time, or its not an its never going to fix things. With all along having to be unplugged from the internet an not able to do my other work needed.

Anyway, I'm not saying I wouldn't do it, but just want to be sure it could be the problem by making sure its nothing else, an like I said, would have to setup a time an last night was not good for that.

Just to mention, I got the MediaPC back at least for now. Basically I did a few things. One I went through all the services on the MediaPC an made sure the same were all set on the MainPC. There were a few things an by reading them, they might have had something to do with things, but I think were low possibilities.

The second thing I did was to run the program you had listed above an per the checks you showed in the pic, an did this for both the MainPC, an the MediaPC.

For both this cleared out all the custom an or proper settings for the IP stuff in the Networking hardware I have, an set everything back to automatic.

Also oddly, for both machines after their reboots, they were not able to go on the Internet. Then after doing the automatic Windows repairs for that in the Network sections, what ever that did, it fixed that.

After that an a reboot of the MediaPC, the connection came back. But that is pretty much normal.

Anyway, at this point as its working, can't really do much.

An I know I'm getting long here, but just to mention or perhaps ask to say, I just wonder why if its a Firewall issue, one, why doesn't this happen right off. Kinda hard to understand if it's not configured to allow a connection, how I can have that for weeks at a time, and then suddenly loose that. To mention, also, I currently am not seeing, nor did I see, any of those issues in the Event Viewer, until the day I lost the connection. So again, if it were the firewall, why didn't it do that for all that time?

To close, I just want to say again, I know you are trying to help an I greatly appreciate it, I really do. An I hope very much I am not coming off wrong in any way by ever questioning things or not doing things.

I guess for now the only thing I can do is wait an see what happens, perhaps the program you linked me fixed things, or perhaps the stuff I did may have an so will just have to wait an see.

Again, thanks for all the help.

As you say not experiencing the issue right away hardens the diagnosis a lot. Sorry for not mentioning earlier, of course disabling firewall is not a good thing, I should have said, disconnect Internet first and then disable firewall.

Hmm, Internet Repair to set IPs to automatic is expected but no Internet access after reboot (with auto config) I don't expect.

Can't say much about why firewall would act after a certain time, a scheduled task interfering perhaps or just a bug occurring.

Keep us posted, and good luck this time :)

Hello GokAy

Has been awhile, but I thought I would update this thread as I think I might have come upon the solution to my problem.

Basically after looking at my MainPC for so much with this issue, I finally began to look at the MediaPC/Laptop unit, an after learning more how to use the Event Viewer, I came upon what I think I remember as a issue with the "ID of 2017, The server was unable to allocate from the system nonpaged pool because the server reached the configured limit for nonpaged pool allocations"

I say I think it was this as I did flush the viewer as I do that to make it easier to see if a issue comes back, but at any rate, I know for sure it let me to info such as this:

Intermittent connection to Windows 7 shared folder from Windows XP workstations - Server Fault

Which basically describes exactly what I having happen.

Think one thing to point out here is perhaps I have even been describing my setup wrong as I really don't know what 100% Networking really is, but really for my use, I was looking to have just one folder be accessible on the MediaPC, from my MainPC, all so I could transfer files to it.

So really what I think I did was just setup one shared folder on my MediaPC, an was looking to have that (or really access to a path to that) show up in my Networking areas of Explorer in my MainPC.

So don't know if that really is 100% Networking the machines, but is what I wanted to have so I could do what I wanted to do.

Anyway, to move on. So from that it describes the solution, which is to go into the Lap's registry an make these changes:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management]
(in my case from the default of "0" to like the above of "1")

(in my case from the default of "1" to like the above of "3")

So I did this an low an behold, I have had a nice two weeks of a solid connection. To which also to add that unlike any times this has happened before, it also has done something new in that while before while I did get it restored, it also would typically show other items in the menu such as things on the network I really didn't want to see, such as my file printer sever unit, an a USB drive I never really use that is plugged into my router. But with this fix is has not shown those things, an just keeps it simple, which is exactly what I have always wanted anyway.

So as I known from before...for me I really need to test this for many weeks as I certainly have had my share of "false positives", but I thought I would post as this one seems pretty good.

One, its issue description really seems right up the alley of what I had going on, two, I have not seen any of the Event IDs I have described in this thread on either machine since, an three it really is showing things in the Explore menu like never before.

Anyway, thought I would post on that to let you know, an help the direction of any others that might be having the same issue an will keep this thread in mind an if this stays this way for long enough that I think it is the resolution, I will list the thread as solved.

Thanks again for all your help
