#1
Fix was a different registry key (affects Windows 7 and Vista):
HKEY_LOCAL_MACHINE -> SYSTEM -> CurrentControlSet -> Services ->LanmanServer ->Parameters
Create a DWORD entry SMB2. Value will default to 0 which is correct.
#2
The SMB2 entry into the registry did not solve the connection issues (out of memory) however it did resolve the issue with the shares disappearing. To solve the out of memory issue (tested working 2 days now) I had to edit a second registry setting.
HKEY_LOCAL_MACHINE -> SYSTEM -> CurrentControlSet -> Services ->LanmanServer ->Parameters
Change the entry ’Size’ from 1 to 3.
