Cannot open dir for a remote location using the perl script

Iam trying to execute a perl script from an ant xml , which would open the directory in the remote location and extract some files. However Iam able to execute the saem script from command line .

The command line works fine as
C:\>perl C:\ICE\scripts\htmlpagesunzip\search_properties.pl \\sjc-filer01.corp.ebay.com\eb_dcpc\v4html_pages  C:\ICE\temp\instance1/v4html

Iam using perl version 5.8.4 from Active Site and I have confirmed that .pl is one if the allowed extensions defined in the IIS Server configurations
C:\Perl\bin\Perl.exe %s %s

The ant xml snippet
 <exec executable="perl" failonerror="true" timeout="800000">
		   <arg line="${global.script.dir}\htmlpagesunzip\search_properties.pl \\sjc-filer01.corp.ebay.com\eb_dcpc\v4html_pages ${global.temp.dir}\v4html"/>
		</exec>
 
I get error as 
[exec] Can't opendir(\\sjc-filer01.corp.ebay.com\eb_dcpc\v4html_pages): Invalid argument
     [exec]  at C:\ICE\scripts\htmlpagesunzip\search_properties.pl line 12

 my $file = $File::Find::name ;

 my $dest = $destdir.$subdir;
 mkdir($dest) unless(-e $dest); # create the folder-structure
 copy($file, "$dest") or warn "$!";
  }
