We begun experiencing a few issues accessing a mapped network drive late in the day after we rebuild a computer that had an OS crash with XP.<br />

We just had to restart the PC in order to &quot;re-establish&quot; the connection because we received the following error:<br />
&nbsp;<br />
&quot;F&quot;\ is not accessible.<br />
The system detected a possible attempt to compromise security. Please ensure that you can contact the server that authenticated you.&quot;<br />
And the only option was to click &quot;OK&quot;.<br />
