If your computer cannot connect to a resource on the network, you may see one or more warnings in the System event log with event ID 3034 and a source of MRxSmb (MRxSmb is the Server Message Block, or SMB, mini-redirector in Windows 2000, with secure SMB capabilities). The description for the event is:

This event is logged when the redirector is unable to make a secure SMB connection to another computer. To determine what actually caused the problem, examine the event log:

1.	Open the particular 3034 event in the System event log.
2.	In the Data box, click Words.
3.	The status code that resulted in the 3034 error is contained in the last DWORD entry in the list.
4.	The status code may be either a Win32 or a Windows NT status code. You can look these up in either Winerror.h or Ntstatus.h, respectively. Both of these files are located in the Windows SDK.
