Cannot authenticate to Windows 2000 share on workgroup after upgrade from Vista to Windows 7
- After upgrading a PC from Vista to Windows 7 (32), I cannot access a share on another computer on my home network (workgroup).
I can see the machine, but it prompts me for a login. I can't login with a pw I know is correct. I've tried win_2000_machine_name\user_name and .\user_name
when I just type in the user name, it assumes it is win_7_machine_name\user_name
I've tried opening up the file share to everyone, but still no luck.
Thanks,

Hi,
Since your system is Windows 7 Home Premium, please
1. Run gpedit.
2. Navigate to:HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa
3. Create a DWORD value under Lsa
LmCompatibilityLevel
4. Set the value to 1
5. Restart

- You could always map the share with a net use command, then connect to it.
I have not had any problems using machinename\usename. I don't have any W2k machines but it works on XP, W2k3 server and Vista.
Bill Please try to change the authentication level to “Send LM & NTLM - use NTLMv2 session security if negotiated”.
Network security: LAN Manager authentication level
Arthur Xie - MSFT- Thanks Arthur.
I can't figure out how to edit my security policy on Windows 7 Home premium. (or how to otherewise change the authentication level) I did manage to fix the exact error mentionned, just follow these steps :
In Windows 2000 server go to start, run, type gpedit.msc and click ok.
Under computer comfiguration, windows settings, security setting, local policies, security options.
Look for LAN Manager Authentication Level. Set it to SEND LM & NTLM - use NTLMv2 session security if negociated. Click OK.
Then run these commands :
secedit /refreshpolicy user_policy
secedit /refreshpolicy machine_policy
Now we have to do the same on Windows 7...
But you run this command to apply the settings : gpupdate /force
You should now be able to access the shares.
Aloha!

- AHA! I tried and tried to run gpedit.msc, but you meant regedit, not gpedit. ;)
and... IT WORKED! Thank you!!! thank you, thank you
I did this part too:
In Windows 2000: go to start, run, type gpedit.msc and click ok.
Under computer comfiguration, windows settings, security setting, local policies, security options.
Look for LAN Manager Authentication Level. Set it to SEND LM & NTLM - use NTLMv2 session security if negociated. Click OK.
Then run these commands :
secedit /refreshpolicy user_policy
secedit /refreshpolicy machine_policy
and on my win7 box, gpupdate /force instead of rebooting (so I wouldn't have to nav back to this site to tell you 'thank you') - this worked for me too...thank you very much and i know a few places to get this word out. thank you again!!!
