We have two LV 7.1.1-built executables running on two different computers that are networked together. Each executable starts the DataSocket Server on their own computer and then attempts to read from the other computer's DataSocket Server. Everthing works well if both computers are running XP SP2 or SP3.
The problem occurs when one of the OS's is Windows 2000 SP3. The executable on the XP computer can see the DataSocket items in the 'DataSocket Select URL' window on the Windows 2000 computer. However, on the Windows 2000 computer, if you open the 'DataSocket Select URL' window, and try to browse the DataSocket items on the XP computer, one of the following dialogs appears:
NI Network Browser Error!
Cannot enumerate items in this hierarchy
Cannot open a network enumeration
0x000004b8
An extended error has ocurred.
OR
NI Network Browser Error!
Cannot enumerate items in this heirarchy
Cannot open a network enumeration
0x00000035
The volume path was not found
This is usually followed by a DataSocket Read error of 214701483 (this looks like a COM object error, but for once, Google didn't have anything to say about it).
There was a similar post to this one in which Manuel Wielander suggests setting the 'Authentication Level' to 'Connect' and the 'Impersonation Level' to 'Identify'. He also suggested adding 'ole.AuthnLevel=1' to the executable's ini file. None of these suggestions work. I have also added every exception imaginable to the Windows XP firewall with no luck.
Anyone dare to step into the networking abyss with me on this one? Much thanks in advance for any help or suggestions.
