Speed dropped thru the bottom, so I did a Rebuild/Repair from a slipstreamed CD. Well, uninstalling the Wireless Card and the On Board Nic, and re-installing seems to have only made things worse. No changes to anything else other than the updates via MST Updater. The info I get back tells me that it's not a big deal error and that I could ignor it, but if I do some file transfers or backup my laptop to workstation, then the event log on the laptop will fill right up with these "MRxSmb\Device\LanmanRedirector HOME NetBT_Tcpip" error 6004, and at that point it's hard to ignor. I am lost as to why this is happening.Īnyone with any idea's or had this problem before.

Lanman redirector drivers#
Have already re-installed drivers on the Dell Truemobil 1180 wireless adapter but made no difference. Now this is a fairly new issue, but I have been attempting to figure this out for sometime now before sending it on to the Big Guns. Not just once, but probably once every 1.5 to 3min. But when I attempt to move files from the laptop to one of the desktops I get the error. Anyway, connecting to the Internet and upload/download no problems all day long. When I connect from the laptop to any of the desktops, I continually get this "MRxSmb\Device\LanmanRedirector HOME NetBT_Tcpip" Event ID 6004 Error is the Event Log.

I also have a XP Pro sp2 desktop and Win 2000 Pro desktop all connected to the router.

+ eryksun, paul.moore, tim.golden, zach.ware, steve.On my home network, I have a XP Pro sp2 laptop connected via 802.11b Dell truemobil 1180 wireless card going to a Linksys router/access point. If we omit the explicit redirector name, then MUP tries prefix resolution, and the error is instead ERROR_BAD_NET_NAME (67): > try: os.stat('// LanmanRedirector/localhos/C$') When we misspell the server name as "localhos", we see that the error for an explicit redirector path, as is used in a mapped drive, is ERROR_BAD_NETPATH (53): ERROR_BAD_PATHNAME, 161) if the redirector name is unknown: The following shows that MUP fails an open with STATUS_OBJECT_PATH_INVALID (i.e. > try: os.stat('// WebDavRedirector/localhost/C$') This open fails because there's no WebDAV server on localhost. The following shows that an explicit redirector path does not use prefix resolution. > os.path.samefile('//localhost/C$', '// LanmanRedirector/localhost/C$') The following shows that MUP parses " LanmanRedirector" as the redirector name, not the "server" component. they are not included in the final path.) Nothing stops us from using this undocumented feature manually in a UNC path, as demonstrated by the examples below. These reserved components are removed from the parsed path, i.e. It also supports an optional second reserved component, with the drive name and logon session ID, such as " Z:0000000000001234". (A valid server name cannot begin with a semicolon, so this syntax is reserved by MUP. "\Device\LanmanRedirector" -> "\Device\Mup\ LanmanRedirector". The provider's device name nowadays is an object SymbolicLink that targets MUP, but with a reserved component that indicates the redirector to use, e.g. It has a sneaky way of implementing this. Since Vista, all redirected create/open requests are routed through MUP, but it doesn't use prefix resolution in this case. Prior to Vista, this used to be a top-level named device such as "\Device\LanmanRedirector" (SMB). A mapped drive sends the request directly to the provider that created the drive. That said, MUP prefix resolution isn't used for mapped drives. As far as I can tell, post-Vista MUP prefix resolution returns STATUS_BAD_NETWORK_NAME even if all providers return STATUS_BAD_NETWORK_PATH. However, since the request is to MUP, the final status is whatever MUP returns. If the "share" component isn't found, it returns STATUS_BAD_NETWORK_NAME. Typically, if the "server" component isn't found, a provider returns STATUS_BAD_NETWORK_PATH. Typically a provider claims the server/share prefix, but the claimed prefix can be just the server, or a variable path length.

"\?\UNC" -> "\Device\Mup") resolves a UNC path prefix to a network provider (e.g. It would succeed if we changed _getfinalpathname to fall back on getting the final name as opened, which skips expanding short component names.)
Lanman redirector code#
A WebDAV share fails the internal request to get a normalized name, as expected for most network providers, but with an unexpected error code that's not handled by the API. (Not that this case would normally succeed. Whereas if I access the underlying UNC path directly the error in this case is ERROR_BAD_NET_NAME (67): For example, I have drive "M:" mapped to WebDAV "///tools", and I see this error if I disconnect the network: Sorry, I mistakenly left out ERROR_BAD_NETPATH (53).
