The report server has encountered a configuration error. Logon failed for the unattended execution account. (rsServerConfigurationError)
Log on failed. (rsLogonFailed)
The report server cannot open a connection to the report server database. A connection to the database is required for all requests and processing. (rsInternalError)
Login failed. The login is from an untrusted domain and cannot be used with Windows authentication.

I did not understand this as I have checked the same report 10 minutes ago. So checked the databases and all the connections. Everything seems fine. Now checked the application logs on the server and the errors came up indicating the service accounts access is denied. I was surprised and asked the System Administrator if the permissions were changed on the Active Directory account. The permissions seems to be fine but for some reason the account is locked out. Upon investigation I realised that one of the administrators was trying to use the SQL service account for installing a new SQL server box and typed the password wrong as many a times to make the lockout happen.

Lessons Learnt
a. create a seperate SQL server account for each Live SQL Server Instance
b. Make sure you dont type the password wrong for the Service accounts

select
OBJECT_NAME(ps.object_id) as TableName
,si.Name
,ps.Avg_Fragmentation_in_percent
,STATS_DATE(ss.object_id,ss.stats_id) as LastUpdatedStatistics
from
sys.dm_db_index_physical_stats(DB_ID(DB_NAME()),null,null,null,null) ps
join
sysindexes si
on
ps.object_id = si.id
and
ps.index_id = si.indid
left outer join
sys.stats ss
on
ss.object_id = ps.object_id
and
ss.name = si.name
where
ps.avg_fragmentation_in_percent > 10
order by
ps.avg_fragmentation_in_percent desc

I published the above query in my Reporting services suite of Operational Reports and check it daily morning. The report shows all the Indexes with more than 10% percent fragmentation along with Last updated Statistics time . If you want to go further.You may want to rebuild all the indexes that are above 20% fragmented in TSQL. If there is a better way of doing it please comment.

Solutions

a.Review the Query and check if it can be better optimised. Some of the Queries’ intermediate heavy datasets are stored in tempdb before returning the results.
b.The most easiest way I found is to restart the SQL Server service. Every Time the SQL server is restarted the tempdb gets flushed thereby reducing all the disk space.

SELECT sysoperators.name AS JobName, sysjobs.name AS OperatorName, sysjobs.enabled, sysoperators.id
FROM sysjobs INNER JOIN
sysoperators ON sysjobs.notify_email_operator_id = sysoperators.id

You need to change the sysjobs.notify_email_operator_id to change the Notifications of the Operator.

But Thanks to Dynamic Management views(DMV) from Sql server 2005.we were able to get the query back from the Cache..The query we used is as follows

select qs.usecounts, cacheobjtype, objtype, qt.text
from sys.dm_exec_cached_plans qs
cross apply sys.dm_exec_sql_text(qs.plan_handle) as qt
–where qt.text like ‘%%’
order by qt.text

and thats it we were able to get back the query…quite cool way of doing things..isnt it?

a. Open Management studio
b. Press Ctrl + Alt+ G (List of Registered Servers)
c. Right Click on one of the Registered Servers –> Properties

Server Properties

e. Once the settings are changed you can see the changes on the status bar as shown below

DECLARE @spid VARCHAR(3000)

PRINT @spid

There are 2 ways

a. xp_fixeddrives — The Easy way

b. Ftsutil(xp_cmdshell) — If I want to know the percentage of free space in harddisk use FTSUTIL . The only thing you need to enable is the xp_cmdshell.

Here is the proc

CREATE PROCEDURE [dbo].[usp_GetDiskSpace]
– Add the parameters for the stored procedure here
AS
BEGIN
– SET NOCOUNT ON added to prevent extra result sets from
