Unable to map to networkshare

We have lost the ability to map a share on one of our servers. It's running 03 sp2, the share security is full ctrl to everyone. There is no firewall on this box. The server also doesn't show up when we try to browse for the share. DNS appears to be fine. Ping resolves to the fqdm. I have disconnected and reconnected to the domain.  Not sure if it's related but we have lost the ability to run tracert through our network. Let me know what other clues I might provide. Thanks.

It sounds as though File and Printer Sharing May either be corrupt or disabled. Ensure that File and Printer Sharing for Microsoft Windows is checked off in your Network Connection Settings, if it is, try removing it and re-installing it.

Thanks, but that solution did not fix the problem, I uninstalled and reinstalled file and printer sharing for ms ntwks, and then repaired the connection. Still unable to map to the share.

can you access the share by browsing to the ip of the server?

\\ip address\sharename

Also try the following:

Check your service to ensure that any services set to start automatically have actually started.

I would also try the following to ensure that some of the windows system files didnt accidentally become corrupted:

Start, run. Type sfc /scannow and hit return. It may take some time to run this, so go grab a coffee.

Let me know how you make out :)

Thanks Binarymime, I am not able to map by ip addr, and I ran sfc and received no errors.

I might of mentioned this machine is a VM. I also set up a FTP server on this box and was able to get to that. Thanks.

We're using VMware Server 1.0.1. The host has 2 vms on it. I'm able to connect to one of the vms' shares, but not the other or the host. FiIe sharing is turned on for all 3. I did notice Vmware Bridge Protocol is turned off on one of the host's VMware Netwk adapters. Not sure I understand this, so I didn't want to turn it on. Thanks for the help.

I have a feeling that may be what is causing your problem. Based on my knowledge of Virtual machines If you want a client to communicate with a virtual machine from a physical client. a bridged interface must be utilized by the virtual machine you are trying to connect to. By bridgning the virtual nic with the physical nic (which is what selecting this option does) you are effectively saying the any request made by a physical client will pass through the physical interface to the virtual nic on the VM.

Is the bridged protocol by any chance disabled on the nic of the VM hosting the inaccessible share?

I turned bridged protocol on and it's still inaccessible. I did notice on some of my other vms that it seems that only one vm shares on a host is accessible. Maybe this is a coincidence, but do you know if multiple vms may be bridged?

There shouldnt be an issue at all in briding multiple machines so long as each machine is using a distinct IP. Each machine should be set to use the briding protocol and set witha unique static IP. From that point any client that you attempt to access Virtual shares from should work so long as you specify the correct machine
