LanmanWorkstation service will not start!

[evilsatan]

This is getting frustrating, I have a Windows 7 machine which will not connect ot network shares even though it can ping the IP/hostname and connect to the web interface using IP.

I found that LanmanWorkstation service is not running, when I click start I get:
windows could not start the workstation service on local computer error 1075: The dependency service does not exist or has been marked for deletion

When I click dependencies I see one listed:
Network Store Interface Service
--NSI Proxy Service Driver

When I look for the Network Store Interface Service I find it is started correctly.

Any ideas how to fix this? The user has no restore points for some reason!!

ust discovered there are 2 'unknown device' in device manager. One is under network connections, Hardware ID is *TEREDO which is to do with IPv6 tunneling. Error:
This device is not working properly because Windows cannot load the drivers required for this device. (Code 31)

The other is an unknown USB device.

EDIT: Just tried disabling Teredo but it still appears in device manager and still LanmanWorkstation will not work:
netsh interface teredo set state disabled

Post the hardware ids of the 2 unknown devices

*TEREDO
USB\UNKNOWN

No great help

I'm going to look at this reg key and see what's in there, the user has no knowledge of a program recently being installed/removed:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\lanmanworkstation

Bit more info, in Event Viewer:
The Workstation service depends the following service: MRxSmb20. This service might not be installed.

I am going to remove that from the dependency reg key and see what happens, will then look at installing the service again as it's for SMBv2

Rebooted and now the same error but specifying MRxSmb10 as the cause...

I know Problem is the client is up by Ipswich and I am currently working frantically to get my job sheets clear by next Weds when I go to Cancun!!

I have a yellow exclamation on all the PCs at my work on the Toledo thing. It's because I disabled IP6 using this method, I think: http://support.microsoft.com/kb/929852

I'm running Win8 and my LanManWorkstation has 4 dependencies:

Bowser
MRxSmb10
MRxSmb20
NSI

If you're wanting to delete/create new services from the service database you need to use the sc command. What I've done before is export the reg key of the service you want to re-create (eg. HKLM\SYSTEM\CurrentControlSet\Services\LanManWorkstation) from a working machine
then delete the service (e.g. sc delete LanManWorkstation)
then create a new service (e.g. sc create LanManWorkstation binpath="%systemroot%\system32\svchost.exe -k netsvcs" type=own depend="Computer Browser" start=auto Displayname="Server")
import the registry settings from the working PC
start the service.

You may have to do this for all the dependencies too. One way of querying the services to see if it's just one component that's failing is by using the sc query command

You can check the state of each service, hopefully one will not be running or failed or something that's obviously different from the others.

sc query nsi
sc query MRxSmb10
sc query MRxSmb20
sc query browser
then sc query lanmanworkstation

If one of the dependencies looks iffy, re-create that one first.

edit: you may also have to reboot after you delete a service before it will be removed from your system properly.

Daft question mate but does it have anti virus on there and if so which one?

Does it have Windows Updates on there, and did it possibly get stopped during one?

Have you tried going into the NIC settings, and then select Client for Microsoft Networks (that's the workstation service under it's posh name) and then do an uninstall.

Bounce the box, and then go back to the NIC properties and do install, and then pick Client for Microsoft Networks and give her a bounce and see what happens?

When doing DRs over the years I saw loads of machines that would feck the stack up - doing the above usually helped a lot for the really dodgy ones

Cheers for the pointers, pretty sure it's mse with updates on. Definitely not norton. Will take a look to orrow but I've told them a reinstall is probs best.
