We have been running Ex03 for 3 years with no issue. We recently added a front-end server to allow OWA from the Internet as well as smart phone access. I am planning the replacement of the back-end server. We do not want to go to 2007 yet. We want to make the availability and fault tolerence as high as possible within our budget. We are getting good hardware but not able to do clustering. We have the database on a SAN and logs on seperate spindles of the back-end server. If the back-end server would totally crash could we use the front-end server to get the system backup as quick as possible? If this would happen the Internet OWA and smart phone access is of low priorty. -- Thanks for your help!!
