I have a fairly beefy MVC4 site running on a Server 2003 box (32 bit). This box is also running our companies main ERP system (including it's SQL Server instance), so it's a pretty taxed box. Occasionally (maybe once a week), the server will basically disconnect from the network, where it starts throwing SQL login errors on sites hosted on that server (including mine), and no one can RDP or access a shared drive on it.
Here are some of the conspicuous errors I've found in the Event Viewer: This computer was not able to set up a secure session with a domain controller in domain due to the following: Not enough storage is available to process this command. This may lead to authentication problems. Make sure that this computer is connected to the network. If the problem persists, please contact your domain administrator.
also: The master browser has received a server announcement from the computer that believes that it is the master browser for the domain on transport The master browser is stopping or an election is being forced.
Anyway, since the issue timing happened about when I first put the site up on the box, it's being looked at as a potential issue. My question is, has anyone heard of anything like this before, or even if it's possible that my site is causing the issue? I double checked, and while the site uses a decent amount of memory (240-260 megs), and some (more labor intensive pages) jack up the CPU to 100% when hammered, it doesn't seem to be a problem immediately preceding an incident.
This issue happened again between 7:30 and 8pm EST tonight. Something to note is I overwrote the site files today (4:30ish EST) with a new build while the site was running and users were connected from a remote location, and it took me ~15 minutes to do it. Not sure if this can cause problems, but I figured I'd add as much info as I could.
Also to note, the nightly database maintenance plan (full backups of all databases on the server) was about 75% complete when the issues started as well
