Windows+2003,+Virtual+Weather+Station+Crashes

Problem
Virtual Weather Station Crashes under Windows Server 2003, Windows Server 2011, Vista or Windows7 when internet functions are performed, like ftp or jpeg file creation.

Discussion
This issue occurs when the desktop images are converted to jpeg files, prior to generating web pages. This is a known issue with Microsoft.

Solution
Add Virtual Weather Station to the list of exceptions to DEP (Data Execution Prevention).

For the purposes of program compatibility, you can selectively disable DEP for VWS.EXE when DEP is set to the OptOut policy level. To do this, use the **Data Execution Prevention** tab in **System Properties** to selectively disable DEP for a program.

For IT professionals, a new program compatibility fix that is named DisableNX is included with Windows XP SP2. The DisableNX compatibility fix disables Data Execution Prevention for the program that the fix is applied to.

If you are logged on as an administrator, you can manually configure DEP to switch between the OptIn and OptOut policies by using the Data Execution Prevention tab in System Properties. The following procedure describes how to manually configure DEP on the computer:

1. Click **Start**, click **Run**, type sysdm.cpl, and then click OK. 2. On the **Advanced** tab, under **Performance**, click **Settings**. 3. On the **Data Execution Prevention** tab, use one of the following procedures: • Click **Turn on DEP for essential Windows programs and services only** to select the OptIn policy. • Click **Turn on DEP for all programs and services except those I select** to select the OptOut policy, and then click **Add** to add the programs that you do not want to use the DEP feature. 4. Click **OK** two times.
