Has anyone else had an unpleasant experience using Microstation XM and Geopak over a VPN? 
 
 
 Well through trial and error we have determined that the main problem lies with the GPK file.

Sorry, no other suggestions.&amp;nbsp; I am only aware of that one becuase it has occured for a number of our users working over wide area networks.
&lt;/p&gt;
&lt;p&gt;
It might be worth a call to technical support and ask to talk with someone familiar with remote access issues.

Thank you for the suggestion Robert! 
&lt;/p&gt;
&lt;p&gt;
&amp;nbsp;I disabled the opportunistic locking for the remote server&amp;nbsp;by following the instructions on this webpage. 
&lt;/p&gt;
&lt;p&gt;
&lt;a href="http://www.dataaccess.com/whitepapers/opportunlockingreadcaching.html"&gt;http://www.dataaccess.com/whitepapers/opportunlockingreadcaching.html&lt;/a&gt; 
&lt;/p&gt;
&lt;p&gt;
Microsofts instructions are here, which included similar details to the data access website. 
&lt;/p&gt;
&lt;p&gt;
&lt;a href="http://support.microsoft.com/kb/296264"&gt;http://support.microsoft.com/kb/296264&lt;/a&gt; 
&lt;/p&gt;
&lt;p&gt;
We tested the connections again by using the plan view and labeler.&amp;nbsp; I felt like it was alittle better.&amp;nbsp; Instead of&amp;nbsp; a&amp;nbsp;3 min delay it was only about 30 sec or more. Still a little annoying.&amp;nbsp;Others still reported having significant delays.&amp;nbsp; One user is running Vista Premium.&amp;nbsp; The rest of us are running XP pro.&amp;nbsp; It didn't look like you can disable the&amp;nbsp;locking in Vista.&amp;nbsp; So the Vista user might just be sol.&amp;nbsp; &amp;nbsp; 
&lt;/p&gt;
&lt;p&gt;
I'm thinking about disabling the windows clients request for opportunistic locking, and seeing if that helps too.&amp;nbsp; Thanks again Robert! 
&lt;/p&gt;
&lt;p&gt;
&amp;nbsp;Any other ideas to help improve the GPK file access over a VPN?&amp;nbsp; 
&lt;/p&gt;
&lt;p&gt;

By default, most servers have &lt;strong&gt;&lt;u&gt;Opportunistic File Locking&lt;/u&gt;&lt;/strong&gt; turned on by default.&amp;nbsp; This causes slow-downs in accessing the GPK because of the way the GPK is accessed.&amp;nbsp; The delays are exaggerated to the bothersome levels you report when using remote access across wide area networks.
&lt;/p&gt;
&lt;p&gt;
&lt;strong&gt;&lt;u&gt;Turn off&lt;/u&gt;&lt;/strong&gt; opportunistic file locking should alleviate the problem.&amp;nbsp; You will probably have to have the system administrator make this settings change.
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
