SUMMARY

You may experience difficulty connecting to computers with HP LAN Manager/X version 1.4. Several different issues have been identified and are detailed with workarounds below.

NOTE: The #NOFNR flag does not apply to Windows NT version 3.5 systems, which do not use directed name queries.

MORE INFORMATION

Idle NetBIOS Sessions Become Unusable After Five Minutes

SYMPTOMS

Idle NetBIOS sessions between Windows NT clients and HP LAN Manager/X servers become unusable after about five minutes.

You cannot connect from a Windows NT computer to an HP LAN Manager/x computer by adding entries to the LMHOSTS file.

You cannot view files on an HP LAN Manager/X server located in a directory that has a name with more than three characters following the period. If you try to run the DIR command a "file not found" message appears.

You may be prompted for a password when you connect from a Windows NT computer to a LAN Manager or HP LAN Manager/X version 1.x server.

CAUSE

HP LAN Manager/X does not recognize NetBIOS "keep alive" messages.

HP LAN Manager/X computers do not respond to directed name queries.

HP LAN Manager/X version 1.4 negotiates by the SMB Specification Ext 2.0 (or LAN Manager 1.x). This specification does not support long file names.



For security reasons Windows NT does not send an un-encrypted password over the network unless you type it in. Since HP LAN Manager/X machines do not support encrypted passwords, Windows NT asks for a password with the following prompt:

   The password is invalid for \\servername\sharename.
   Type the password for \\servername\sharename:
                



Solution:

Typing the correct password will allow you to log in.

WORKAROUND

Disable NetBIOS "keep alive" messages in Windows NT by using the following procedure:

WARNING: Using Registry Editor incorrectly can cause serious, system-wide problems that may require you to reinstall Windows NT to correct them. Microsoft cannot guarantee that any problems resulting from the use of Registry Editor can be solved. Use this tool at your own risk.

  1. Start Registry Editor.
  2. Go to the following key:

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services \Nbt\Parameters

  3. Choose Add Value from the Edit menu.
  4. Add a value using the following information:

          Value Name: NbtKeepAlive
          Data Type:  REG_DWORD
          Data:       0
                            
  5. Exit Registry Editor.


Cannot Connect Using LMHOSTS File

Add the "#NOFNR" flag to the LMHOSTS entries for these computers. For more information see article 103765 in the Microsoft Knowledge Base.
