NW 6.5 SP3, 2 Node Cluster, NSS with compression activated
Windows XP, SP2, NW Client 4.91 and other Hardware / Software combinations

When I try to copy compressed files to a local disk, I get an error "Source
file or Source Harddisk can not be read" (translated from geman to english).
After the first access the file colour (in windows explorer changes from
blue to black [normally means commpressed to uncompressed]).
When I try to copy the file now, it is working.

Any idea?
