replicate physical network connection state

What is this in VmWare Workstation?

Replicate physical network connection state — Select if the virtual machine uses a bridged network connection and if you use the virtual machine on a laptop or other mobile device. As you move from one wired or wireless network to another, the IP address is automatically renewed.

Windows NT user or group 'Domain\User' not found. Check the name again. (Microsoft SQL Server, Error: 15401)

This error was reported by SQLSERVER....

The actual problem was due to a duplicate SID in my windows machine.

How did this duplicate SID issue come up? I found that it was because this machine was due to cloning another Virtual Machine.

The solution is to run SYSPREP...It generates a new SID. But,beware....You can only do it thrice on a Windows 7 pc.

Really wish we had errors that were more user friendly in Windows.

The type or namespace name 'Web' does not exist in the namespace 'Microsoft' (are you missing an assembly reference?

You added reference...but still get that error?

The solution : Choose the right .Net framework.

Don't use ".Net framework 4.0 client profile"...Use ".net framework 4.0" in your Application Configuration.
