Trying to connect to a Windows 2000 share results in your credentials not being accepted.

  • Fantastic man, thank you for this. I know it is a couple of years old, and yes I still a have a couple of XP machines. I can't get it to work both ways, but the Win7 can see WinXP just fine. Thanks again for the info!!

  • Worked here, although I had no clue about how to get into Local Security Settings (Tim posted that elsewhere, it turns out) and I also don't know how I changed the setting, but somehow it did change and now I am back to my previous access to my Win2k machine. The other question is how I LOST that access and hence needed to go this route--no idea. Anyone know? Was it a Win 7 update? Thanks very much, Tim.

  • Okay I just had this same issue - cannot connect my Windows 7 Home Premium machine to my Windows 2000 machine. Home Premiun does not have the local security policy manager so you need to do it through your regedit command. I just did this and got it to work and I would consider myself a novice at this stuff. So here is the regedit way: Click Start - type in regedit at the search prompt - open regedit. Click on HKEY_LOCAL_MACHINE then SYSTEM then CurrentControlSet then Control then LSA. On the right half there should be a bunch of names and types. You need to add a new DWORD to the list so anywhere in the right half right click and hover over "new" and select DWORD (mine said DWORD 32-bit value). Cut and paste this in the name of the new DWORD you are adding without the quotes "LmCompatibilityLevel". Now if you look under the column Data it should read 0x00000001 (0). This needs to be 0x00000001 (1). To change the 0 to a 1, right click on the LmCompatibilityLevel name you just added and select Modify. Change the Value data: from 0 to 1. My Base was checked as Hexadecimal. Click OK. Close out of the Regedit. Reboot your machine and whalla it should work. I saw a couple of other threads that recommended changing the value to 2 but 1 worked for me. Happy trails. Kevin

  • How do you do it with Windows 7 Home Premium?

    2011-05-10 07:29:37

  • Great, except for the fact that there is no Local Security Policy Manager in Windows 7 Home Premium. Do I have to get Professional or Ultimate to get this to work?

  • HUGE THANKS! That fixed my problem at several locations. I'm sure glad Microsoft documented this so well....NOT! Cheers!

  • It's worked! Thank you very much. :)

Windows 7 has the ability to allow you to access your Media Library from a remote machine over the internet. To do this, you need to configure media sharing on both the machine to share the media and the machine to access the media.



What you will need:
• 2 computers connected to your home network and joined to your homegroup. (A desktop and laptop work great.)
• A Windows 7 Online ID Provider. At this time, only Windows Live is supported.
• A UPnP capable router or the ability to statically forward ports to your computer.
• For testing, you will need a computer not connected to your home network, but a member of your homegroup.

Configuring your home computer:
• Open Windows Media Player.
• Open Your Library (Press, the ALT key, choose View - Library).
• Click the down arrow beside the word Stream and choose Allow Internet access to my home media...

• Choose Allow Internet access to my home media again and follow the instructions for linking your Live ID to your media library using the Windows Live ID Sign-In Assistant.

Configuring your remote computer:
• While connected to your home network, verify the remote computer is a member of your homegroup.
• Verify that you can see your home machine under Other Libraries and are able to access and play music.
• Follow the instructions above to link your remote computer to the same Live ID as your home computer.
• Connect your computer to a network other than your home network.
• Right-Click on Other Libraries and choose Refresh Other Libraries.
• If you have successfully configured things, you should see your home computer.
• Note the world icon that I have highlighted on the left. That means you are connected over the internet.
• To verify, right click on a song and choose properties, it should start with dlna-playsingle://.

Troubleshooting:
• I had trouble with my Linksys WRT610N and the SPI firewall. With it enabled, media sharing would not work and I could never get my home machine to display in my remote media player. As soon as I disabled SPI Firewall, my home machine became immediately accessible.
• If you would prefer to forward ports manually rather than enable UPnP, follow this guide.
