RasEnumEntries returns only 1 dial up entry (PocketPC)

P: n/a
No matter how many dial up networking entries I have, the
RASWrapper.RasEnumEntries(null , null , entryNames, ref cb, out
entries); always returns the right number of elelments in entryNames
but only the first element has the connection name in it. Any idea why
this is? Thank you for your help.

Some code for your reference. let me know if you need more code:

Some more clarification: this code works fine on 32bit and 64 bits
PCs, but it doesn't work for PocketPC. Is there anything I'm doing
