Minimums for simple use of RDP

[Pete Helgren <pete@xxxxxxxxxx>]

 I am temporarily at a customers site and would like to use RDP just to 
locate and browse source members.  I *was* initially successful in doing 
so but lately the connection won't retrieve a source member.  I can 
connect to the i (270 at V5R4M0) and I have several filters in place and 
I see the objects I want.  But, when I double click the source member to 
view the contents I get the following error:

RSEF1002 Operation failed. File system input or output error.  The 
details shows: Message reported from file system: Unable to establish a 
connection.

The RSEF1002 seems to indicate that there is a connection issue but the 
connection is obviously working since I can drill all the way down to 
the source member in the file (just can't open it). The DDM server is 
running and I have *ALLOBJ authority.  It's weird because this was 
working for the first few days I was here and now it stopped working.

The verify connection option returns a list of Products and PTF's that 
need to be applied but since this is just a temporary gig, I don't want 
to go to the hassle of finding the install media and then downloading 
and applying PTF's (assuming that it is a PTF issue).

All I really want to do is browse the members for convenience.  Is there 
a short cut way of getting this to work (since it *was* working) or 
should I just stick with SEU?
