Ed:

I'm still having the same problem. Here is an example:

= aPrinters(bob)
&& bob[1,1] = "HP 4050T PS"
&& bob[1,2] = "Ne00:"
&& The printer is \\hmaserv01\hp4050

Declare integer WNetGetConnection IN WIN32API STRING @, STRING @, INTEGER @

cUNCBuffer = REPL(CHR(0), 261)
nLength = LEN(cUNCBuffer)

cLocalDevice = "Ne00:"
? WNetGetConnection(cLocalDevice, @cUNCBuffer, @nLength)
&& Error 1200 - unknown device

cLocalDevice = "HP LaserJet 4050 T PS"
? WNetGetConnection(cLocalDevice, @cUNCBuffer, @nLength)
&& Error 1200 - unknown device

cLocalDevice = "L:" && a mapping
? WNetGetConnection(cLocalDevice, @cUNCBuffer, @nLength)
&& Returns proper UNC

I'm not sure what I'm missing, and I hope you can help.
