Every once in a while, I get a client PC that won't be able to log into the domain. This morning it was telling us that the trust relationship between the pc and the domain failed. I checked the event logs on the primary domain controller and I see this for 2 PCs (the one that had the problem and one that can log in today).

The session setup from the computer failed to authenticate. The name(s) of the account(s) referenced in the security database is . The following error occurred: Access is denied.

I know how to fix this, by rejoining the PC to the domain... But why does this happen and how can I prevent it so I don't have to keep rejoining PCs to the domain?

My technical support staff is only a little familiar with IIS and that's only as far as install goes. They need to install/update and configure ASP.Net web applications and WCF services that we write. Does anyone know any good tutorials/books/web sites that can help them understand some of the basic concepts of web applications and maintaining them on IIS?

We have Windows Essential Business Server 2008 up and running after upgrading from a Windows 2003 domain. Everything is working fine, except new users! Every time I add a new user, I set the log on to restrictions to allow them to log into any computer. As soon as they log into one machine and then log out, the now get restricted to just the servers in our domain, not any of the workstations. I can't seem to find a policy that has this setting. How do I get this to not reset those log on to restrictions?

I have Windows Server 2008 R2 installed and running. I created a full server backup to an external portable drive (MyBook by WD). It scheduled and has been running with no errors for a week. I purchased another MyBook (same size too) to swap out so we have an offsite backup in rotation. I plugged the new drive in and ran through the wizard to add this drive as a destination. It gets to the end and says "The filename, directory name, or volume label is incorrect." Then says the backup has not been modified.

If I look in the disk managment, the external drive has been formatted and labeled exactly like the first drive, only with Disk_02 instead of Disk_01.

This is the second drive it has happened on. We had another drive that I assumed was just going bad so we bought this new one to replace it.

Edit: Also, this type of scenario was working just fine on a Windows Server 2008 machine. The boot drive went bad so I decided to start over with R2...

I have an existing Exchange 2003 server running on Windows Server 2003. I am in the process of replacing our current server infrastructure and virtualizing it all in Hyper-V.

I have Essential Business Server 2008 installed in 3 separate VMs and running. Everything seems to be working fine so far.

I am now trying to migrate my exchange mailboxes over to the new exchange server in the messaging server and every time I try I get this error: MapiExceptionNetworkError: Unable to make admin interface connection to server. (hr=0x80040115, ec=-2147221227)

I have done some searching and found solutions like adding the computer to the exchange domain servers groups and install group, also making sure the user logged into the new server is in the proper groups. I also saw a solution in making sure that any unused NICs are disabled. I've tried all that to no avail.
