I've been reading about the TCP protocol recently because I was a little curious about how and why certain flags were used.

In the information I found it talks about a normal close TCP FIN should be used to close a connection but then it also talks about TCP RST can be used for an abortive close on an active connection.

My question is, why would one use a RST to abort/close an active connection over using TCP FIN?

(Referring to an active connection as a connection where both endpoints sent and received data after the standard 3 way handshake. I know a RST can be used by the server when a client sends SYN for a server port that is not listening)

I have Win7 Ultimate 32-bit running and I am trying to enable Bitlocker on the system drive. The system is running in a Win2003 Domain. I have been successful at enabling Bitlocker on other Win7 systems running in the same domain (mix of 64-bit and 32-bit).

When I use control panel to "Turn On Bitlocker" from a domain admin account I get an error during the system requirements check. "Changes made to your system require that you restart before running Bitlocker Setup." Problem is, I've already restarted, several times, none of which resolved the problem.

I have had Bitlocker running in the past on this system with Windows Vista Ultimate 32-bit so I know the hardware can handle it. I'm not sure what else to try. Any ideas would be helpful.

Thanks,

Last week we started getting the following error in the event log. "Error initializing session for virtual machine MAINSERVER. The error number is 0x8004011d. Make sure Microsoft Exchange Store is running."

The Exchange Store service IS running. We are not experiencing any problems in the operation of Exchange 2003. We are able to send and receive emails without problems.

This occurred after we ran recovery from a hard drive failure. Some mailboxes had to be re-created and their content moved back to the server from the blient cache. These users do not experience any issues.

What would cause this in the event log is there is no apparent problem?

Thanks for any ideas
