Hyper-V Client Display Resolution and Installation of Integration Services on VM

1600x1200 is the limit. RDP is your only option to exceed those dimensions.

Make sure after the OS is set up, you have installed the integration services. Tips: Remove Windows Server 2008 installation DVD from VM DVD drive by selcting Media >> DVD Drive >> Eject 

Then select  Action >> Insert Integration Services Setup Disk

Restart the system after completing the installation of Integration Services.

After successful setup of Integration Services:

*You could use mouse to work with VM through "Virtual Machine Connection".

*VM must allow network connectivity as NIC drivers were installed.

*and some typical Hyper-V Windows services running in the guest OS:

Change the display resolution before connecting RDC

click the options

and select the required resolution and then connect to the client. If 1024x768 is selected then client screen resolution will be also the same.

  

check the screen resolution now

if resolution 800x600 is selected the client screen resolution would be 800x600.

This may be the recommended screen resolution for some of the applications to get correct output. So this is how you adjust the resolution of client vm.

Important Checklist to Install SQL Server 2008 R2 Failover Cluster on Windows 2008 R2 Failover Cluster

   

Preparing server from scrap.. lemme prepare the checklist first..

in a nutshell...

1. Configure RAID – for OS redundancy make sure disks are on raid 1 or 5 selection.
2. Install Windows Server 2008 R2 Ent Edn.
3. Register OS online
4. Install latest patches including SP1 available at the moment.
5. Change the windows updates schedule.. Change settings and choose download updates but let me choose whether to install them. This way it would be a controlled restart.
6. Join node to domain
7. Install Anti-Virus
8. If using SAN Storage to present the storage disks to the server you may need to download and install HP MPIO Full Featured DSM for P6x00 family for Disk Arrays. This will present the EVA 4400 SAN Storage Disk to the Server. Or use free iscsi storage initiators see this one.  Present it to the server. Format (ntfs) the newly created disk drives. Total 4 drives preferably. i) for Quorum (max 1GB enough),  ii) for MSDTC (max 1GB enough), iii) for Log Volume, iv) for Data Volume.
9. Create a cluster account and add to domain admin group.
10. Node1: Add Features Failover Clustering
11. Go to network connections and disable not in use network adapters. Select detailed view and disable netbios on heartbeat network of each nodes. Go to network properties>>ipv4 properties>>advanced>>wins>>disable NetBIOS over TCP/IP.
12. Node1&2: Add Application Server Role  and Distributed Incoming Remote and Outgoing Remote Transaction Role and .net framework 3.5.1 feature from Server Manager.. if required make sure non-http activation is selected which is used for WCF activation.
13. Refer Security considerations before & after SQL Server Installation
14. SQL 2008 R2 – proceed with system configuration checker
15. Avoid SQL server setup run from remote share.. copy the ISO image locally and run the setup. installation will be faster this way. if required download ISO magic disc for accessing ISO images.
16. Install SQL, option: New SQL server failover cluster installation .. Point Data Drive to S.. Point Log Drive to L: If skipped you can do this at a later stage from
17. Add mix mode authentication..
18. Setup preferred Cluster Node to the more powerful server (say cluster node 1 has more memory, so make it as the preferred owner).
19. Group Policy inclusion.. refer automatic restart of service accounts i) Log on as a batch job, ii) Log on as a service, iii) Act as part of the operating system
20. Present disable non present network drivers.
21. Enable windows firewall and include only required tcp port
22. Install SQL to the second node. .option: add node to a SQL server failover cluster
23. Segregate SQL service account  and include the domain service account credentials for each service. note that passwords are changed once in 3 months (production servers only) or based on companies IT policy. 
24. If you want SQL named instance on this failover cluster then at this point select the option 1 from SQL setup: "new installation or add features to an existing installation".  At command prompt type ssms (for SQL 2008 onwards) or sqlwb (for SQL 2005) and check the connections. You may remotely check the connection by typing "telnet servername port" (default 1433).
25. Finally remove internet access from SQL server to minimize external threats.

The credentials you provided during SQL Server 2008 installation are invalid

When providing service accounts and passwords you might encounter one of the following error messages, which prevents you from continuing the installation:

- The credentials you provided for the SQL Server Agent service are invalid. To continue, provide a valid account and password for the SQL Server Agent service.

- The specified credentials for the SQL Server service are not valid. To continue, provide a valid account and password for the SQL Server service.

Solution: you may select NT AUTHORITY\SYSTEM and proceed. Later you can change the SQL service account with a dedicated domain service account meant for starting the service.

you can also provide the account with specific roles, like local admin, domain user/ admin based on org. and application specific requirement.

Recommendation:

Automatic restart of Service Accounts

Always make sure that if you are using domain account for running the SQL service, that account needs to be part of following 3 main resultant policies (you might have to do this from AD Group Policy to automatically reflect to the joined servers):

i) Log on as a batch job

ii) Log on as a service

iii) Act as part of the operating system

This will make sure that the account with which the SQL services run are automatically started after each system reboot.
