Mani's questions

I have two windows 2008 R2 Terminal servers and have given users access to both server to keep redundancy/ load sharing.
How to restrict users from logging on both servers at same time?

I am setting up a simple site which shall contain some static file and I want to enable directory browsing plus this site should be available to all.

1. Whenever I enable directory
   browsing it creates a web.config
   file, (I don't want it). now I can browse the site. so far OK.
2. I share the folder to allow access to a
   group, now this site stops working and
   throws 500 error.

Server is windows 2008 R2, IIS 7.5

Size of distribution database used in transactional replication has increased significantly, it is almost double of the database being replicated. Size of replicated database is 18 GB and distribution database is 35 GB.

Is this normal? If so can someone point me to resources where I can get some information about how to assess size of distribution database in future.

Please note, it is SQL 2008.

I am planning to buy a new server with hope of having better performance. I do not intend to have any other service/application running on this server. Hardware configuration has been already finalized.

This will be dedicated SQL server. It will be very helpful if someone can list

1. What options to be chosen while installing SQL server enterprise 2005?
2. What option to be chosen while installing Windows 2008 R2?
3. what all services I can disable to improve performance?
4. Any other optimization technique...

Please note this server will also replicate itself (transaction push replication) to another SQL Server 2005 which will be a reporting server.

Edit1

1. Will use SQL 2008.
2. Storage is 160 GB fusion-io ssd io drive for databse , intel 64 gb ssd for OS and program.
