Tomcat Service and Shared Drives?

Hello, 
 
One of my SOAP applications needs to read in files on the disk. These files
are located
on a shared drive (K: in this case mapped to \\myserver\files
<file://\\myserver\files> ). So, for example, the SOAP
application may have to access a file called k:\data.txt.
 
I have noticed that, whenever I run Tomcat as a service, I get the following
exception:
 
"The system cannot find the file specified."
 
I know the file exists and if I move the file to a local drive (c:\files\)
then everything is
fine.
 
The strange this is, however, if I run Tomcat from the console (batchfile)
and not as
a service then everything seems to work fine!?!?

The bottom line is this. It appears that my application cannot access shared
drives
when it is run within a Tomcat service, but it can access shared drives when
run from
the console.
 
Any ideas?
 
Thanks!
