Central console enables us to see all of the activated and deactivated computers but it has poor alerts and frustrating technical support

The solution needs to allow for other company product licenses to be included if possible. The solution needs to include other Microsoft products, like Exchange, SharePoint, etc. Right now, it's only for Windows and Office. The solution needs to be made web-based. Right now, we have to install some tools and to use these tools we have to log into a specific server. If that server has an issue we cannot manage it. The solution needs to be able to be managed from any machine. Alerting capabilities should be improved. If a license expires or there is a breach, or something is non-compliant, the solution should send out alerts.

Pricing and Cost Advice

"I give the price of the solution a five out of ten."

"The tool is included with Windows."

"There is no license required for the product as it is role-based. Whenever you go for a Windows platform server, the role has to be installed directly from the server manager. There is no additional cost that has to be paid for that. It is free to use."

"The solution’s pricing is yearly. The pricing is affordable and not high."

"The price of Windows Server IIS is expensive. They have a large user base, and they charge a little bit too much."

"The tool's pricing is on a yearly basis."

"IIS comes along with an OS license from Microsoft. Others can opt for a perpetual-based licensing model to be able to use the system."

"The product's price is not high."

Overview

Internet Information Services (IIS) provides a secure, easy-to-manage, modular and extensible platform for reliably hosting websites, services and applications. With IIS, you get choice and control without giving up reliability or security.

Microsoft

Windows Process Activation Service generalizes the Internet Information Services (IIS) process model, removing the dependency on HTTP. All the features of IIS that were previously available only to HTTP applications are now available to applications hosting Windows Communication Foundation (WCF) services, by using non-HTTP protocols. IIS 7.0 also uses Windows Process Activation Service for message-based activation over HTTP.
