This is fixed in charm cvs version. Basically charmrun treated your "
\\winclus\share\namd\namd2" as a relative path and added the current
path "Z:\namd" in front of it.

You can also modify your code in charm/src/arch/net/charmrun/charmrun.c,
around line 796 to:

#if defined(_WIN32) && !defined(__CYGWIN__)
  if (argv[1][1]==':' || argv[1][0]=='\\' && argv[1][1]=='\\') { /*E.g.:
"C:\foo\bar.exe*/ <<<<<<<<<<<<<<<<< REPLACE
#else
  if (argv[1][0]=='/') { /*E.g.: "\foo\bar"*/
#endif
          /*Absolute path to node-program*/
    arg_nodeprog_a = argv[1];

Just replace the second line above.
