Error creating Tablespace on Windows

Hi,

I am getting this permission denied error on Windows 2008 trying to create
a tablespace.

template1=# create tablespace testtablespace location
'c:/windows/temp1/testtablespace';
ERROR: could not set permissions on directory
"c:/windows/temp1/testtablespace": Permission denied

If I use 'c:/windows/temp/testtablespace' for location, it works.

If I look at properties for c:/windows/temp and c:/windows/temp1, they look
identical (same ownership and read/write permissions).

Any thoughts on what else to check?

This is with Postgresql 9.1.9.
