We can increase the time that is allowed to process ASP scripts for a particular Web site by changing the metabase value in IIS.
To perform this, follow below steps,
====
Open Internet Services Manager(IIS)-->right-click on the Web Site.
Select Properties-->Click the Home Directory tab-->Application Settings--> Configuration.
Under App Options tab. Increase the ASP Script Timeout value to a number high enough to prevent script timeouts.
