mrlifeguard has asked for the wisdom of the Perl Monks concerning the following question:

Hi, I'm a first time poster, long time reader. I have a problem connecting to other stations on my lan network. I am trying to view a reg value from these stations. I am using ActivePerl and installed Win32::Tieregistry using PPM. When I try to connect to another station, it keeps on giving me errors or it simply cannot connect. I have no idea what the problem is and I have tried everything. I often get an error saying something about conflict with an existing I/O operation. Here is my script for the remote registry connection: 
use Win32::TieRegistry( Delimiter=>"/");

$machine="A";
$path='LMachine/AA/BB/CC/';
$remote_key = $Registry->Connect($machine, $path, {Access=> KEY_READ})
+or die "Can't read $root_key ";
$remoteData= $remote_key->{"/value"}
    or  die "Can't read ServerA's value";

[download]
After running it, it only displays the "Can't read $root_key" Is it because I'm using a WINXP machine to connect to a Vista machine? Also, do I have to worry about username/password for the station I want to connect to? Please help me out! Thanks! CJ

    I often get an error saying something about conflict with an existing I/O operation.

    Where are you seeing that message? When, (ie. after which operation in your code) is it displayed? What is the exact text of the message?

    Print the error messages (using $! and/or $^E (I find the latter most useful under win32), as a part of your die messages: 

    ... or die "...: $! [$^E]";

    Then you'll be able to tell us what the error actual message is, and we stand a chance of helping you. The likely problem is that you don't have the appropriate permissions, or you've supplied a bad machine name (Do you really have a machine named "A"?), but the exact text of the message would identify the cause.

      Hi, This is the error message: "Overlapped I/O operation is in progress". This happens when i try to connect to the remote machine. The machine name is correct, as well as the path.

        Check the event log of the receiving machine.

        If you see "Event 36; ...the configured identity is incorrect...", you may have a conflict in the passwords which are supposed to be shared by IIS, DCOM and MTS, but got out of sync.

        More info on this in MS KB article 297989.
