Windows 7: Mapped network shares disconnect after a few minutes.

18 Dec 2011   #1

Windows 7 Ultimate x64
Mapped network shares disconnect after a few minutes.

Hello all, I have two machines. 1 Win XP SP3 as a Media Server and Win7 Ultimate x64 as my primary workstation. The XP box has shared folders that host all my media content. The Win7 machine has mapped drives pointing to those shares.

Here is what's happening:
On my Win7 machine I access the media share and play a movie. The movie will play for around 14 minutes then I'll receive errors that the file cannot be found. I open Win Explorer and find the mapped drives have disconnected.

What I have done:
I have followed the steps in this MS article: Mapped Drive Connection to Network Share May Be Lost With no luck.
I have tried everything suggested in this MS technet thread: Loss of mapped drive, networked drive disconnects
I have set the local policy on both machines to have a maximum session idle limit of 99999 minutes. no luck with this either.
I have disabled my Comodo firewall on both machines. no luck.
I have disabled my Windows firewall on both machines. no luck.

Any ideas?

Welcome to Seven Forums,

Your Comodo might be intervening, I would considered uninstalling it by using Free Revo Uninstaller.
Download Revo Uninstaller Freeware - Free and Full Download - Uninstall software, remove programs, solve uninstall problems

An update will be appreciated.

Thank you for the reply. Unfortunately, I don't believe the Comodo is the problem. I am able to access the media from my Ubuntu laptop and watch movies with no issue. I believe it is isolated to the Windows 7 machine.

Edit: It seems you may be correct. I am testing now but I found that if I disable the win firewall and comodo firewall on the xp box but leave them enabled on the Win 7 box I can watch media with out interruption. So far I have tested for 30min, much further than before. I will update again when I have concluded testing.

If Comodo is an issue, then please follow my suggestion. Your Windows Firewall would do an excellent job protecting your computer. Just exclude the Ports or Programs needed to run.

I had a similar issue caused by power management settings recently.

Thanks for all the replies!
2xg, as you suggested I looked into the Comodo firewall more and found it to be the issue. After adding my LAN subnet to the trusted zone in Comodo my disconnect issues are gone.
