[Samba] Windows 7 client losing trust with domain

[Daniel Müller]

I had the same Problem, fixed it with this registry-hack:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\LanmanWorkstation\Parameters]

"DomainCompatibilityMode"=dword:00000001 
"DNSNameResolutionRequired"=dword:00000000 

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\] 
“LmCompatibilityLevel”=dword:00000000 
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\Netlogon\Parameters]

"Update"="no" 
"DisablePasswordChange"=dword:00000000 
"MaximumPasswordAge"=dword:0000001e 
"RequireSignOrSeal"=dword:00000001 
"RequireStrongKey"=dword:00000001 
"SealSecureChannel"=dword:00000001 
"SignSecureChannel"=dword:00000001

Good Luck
