I would love some more information about the settings before I just apply them, so I know what I'm doing. The closest I found was this, but it doesn't seem to match up with the settings you answered with:

Those reg keys were referenced to up to W2003 AFAIK. Explanation is found here: http://technet.microsoft.com/en-us/library/cc784562%28WS.10%29.aspx.
The values given above do not make sense to me, as to Large System Cache can either be enabled or not, but not configured further.
If you increase the file cache allocation units, you will experience a slow-down of applications, so you should be careful about settings.

I believe you are on the right track but like you jessc7 I am working with Windows 7 x64 and the keys referenced here are for previous versions of windows. I think I found the correct keys but I won't be able to verify that until tomorrow when I'm in front of the computer. The closest information I found was for Server 2008. The following link talks about keys that are no longer used and the keys that are currently used for Server 2008. The main information is in the charts.

1UpTech, any luck?
I have changed the LargeSystemCache setting only, and since that no according error messages anymore (W7 Prof x64, 8 GB), while prior it did not last more than one day to get them.

Any noticeable negative system/application impact?
Nope. There shouldn't be any side effect as long as there is enough memory.
Disable Bonjour. Right click computer and click manage. On the left side drop down services then click service to see the service on the right side. The very first entry has a weird name it's like _76582#_38943 some junk like that. This is the bonjour service. Double click it to open it. Stop it then disable it. This change along with the LargeSystemCache setting stopped my disconnect issue and the error messages.

I currently only have 3 GB in this particular machine, even though it is 64-bit. How can I determine if I will run into performance issues with the LargeSystemCache change?
@1UpTech: I don't have Bonjour installed, but glad to see your error when away by applying both changes.

I didn't have bonjour installed either. On a fresh install that service was there but not listed in add/remove programs.

Apparently you need to tell Windows that you want to use the machine as a file server and that it should allocate resources accordingly. Set the following registry key to 12:
HKLM\SYSTEM\CurrentControl
and set the following registry key to 32:
HKLM\SYSTEM\CurrentControl
After making these changes and restarting, I havent seen this issue arise again. Fixed!
