Error open/accessing a MSSQL Linked Server

Hi!

Im having the fallowing error when I try to open/access a linked server
Error:
Error 7302: Could not create an instance of OLE DB provider 'MSOLAP.2'.
OLE DB error trace [Non-interface error: CoCreate of DSO for MSOLAP.2 returned 0x80004005].

I have already tried to create the server using SEM and also with SQL syntax in ISQLW.
Code:
EXEC sp_addlinkedserver
@.server='LINKED_OLAP',
@.srvproduct='',
@.provider='MSOLAP.2',
@.datasrc='MyServerName.MyDomain,
@.catalog='MyDataBase'

Im allowed to create the linked server but I cant use it.

Information:
OS: Windows 2003EE
SQL: MSSQL 2000 + SP3a
MDAC: MDAC2.8 rtm

Thanks,
Paulowhen referring to objects defined in a linked server, you should use the convention:
servername.databasename.userid.object|||That it's not the problem for sure.|||I'd see if any of Microsoft's (http://search.microsoft.com/search/results.aspx?view=msdn&st=b&na=82&qu=0x80004005+OLAP&s=1) ideas help.

-PatP|||Thanks, but none of the links apply to.

Error Message when accessing Report Manager

Whenever I try to access Report Manager, I get this message. I don't know what caused it. I recently installed Crystal Reports v11 & Oracle 10gEX evaluation apps. Could they have caused this? How do I fix this?

Product:SQL Server Reporting ServicesEvent ID:rsReportServerDisabledSource:Microsoft.ReportingServices.Diagnostics.Utilities.ErrorStrings.resources.StringsVersion:8.00Message:Unable to encrypt or decrypt data managed by the Report Server instance. Please refer to the Reporting Services online help for guidance in enabling this functionality.

Explanation

A symmetric key is a single key used to encrypt and decrypt data. Reporting Services encrypts the symmetric key itself, using the public key of a specific user account on a specific computer. This error occurs when the public key that the user account provides does not match the public key that report server is expecting. Conditions that cause this error to occur include changing the name of a report server instance, moving the report server instance to a different computer, or changing the account under which the Report Server service runs.

User Action

A system administrator on the computer running the report server service can use a backup copy of the public key to get the report server running again. Use the rskeymgmt utility to apply the backup key set. If you do not have backup of the key, you must run the rskeymgmt utility to delete all of the encrypted content, run the rsconfig utility to respecify the encrypted connection values used to connect to the report server database, restart the service, and retype stored credentials for all reports that use stored credentials. For more information this utility, search Books Online.

---

The encryption keys are tied to the service account user. If any of those programs reset the ASP.Net account, it would cause this error.

Have you tried following the steps listed under "User Action"? Depending on which accounts were reset, you might be able to use rsactivate -r if you do not have a backup key.|||Brian:

Pardon my lack of knowledge but exactly how does one access the "rsactivate -r". Do I type this into the "run" text block?

I have found the rskeymgmnt.exe & rsconfig.exe files. Rvery time I click the executable the command window pops open & immediately closes.

I apologize for asking such elementary questions but it is difficult to get answers outside of the expert forums.

Thanks, Jack|||Brian:

Can you tell me how to retrieve a backup key? I default installed SQL Server 2000 and later Reporting Services. I do not recall setting up a backup key. Can I use rekeymgmt -e to extract a key to a text file? Can I use rekeymgmt -a to apply it before I try to get into Report Manager?

When you say "any of those programs reset the ASP.Net account", I assume you are referring to either Oracle Express or Crystal Reports?

Do I type rsactivate -r into the "run" text box? Do I type any other characters with it? Do i need to type a specific account name with the reset commandor will a generic "rsactivate -r" reset all.

I am obviously a beginner. I would appreciate the help.|||Rsactivate and rskeymgmt are command line tools. You will want to open a command window and run the programs from there. You can run rsactivate /? and rskeymgmt /? to get more help on other flags you will need. Also see the MSDN documentation at http://msdn.microsoft.com/library/default.asp?url=/library/en-us/rsuiref/htm/cpu_rsconfig_v1_6yqq.asp and http://msdn.microsoft.com/library/default.asp?url=/library/en-us/rsuiref/htm/cpu_rsconfig_v1_29ly.asp for example usage and a description of what the various flags do.

You should try looking in the SSRS logs to see if it gives you any
descriptive information (normally located in: C:\Program Files
\Microsoft SQL Server\MSSQL.2\Reporting Services\LogFiles ). If you
cannot resolve the issue by looking at the logs, you should look into
reinstalling SSRS. Hope this helps.

Error message

We are running Access2000(front-end) SQL server (backend). When we try to
either compile or run an ADE, we receive the message "Error Accessing File.
Network connection may be lost". When you go to File-Connection-Test
Connection- the message "The connection succeeded" pops up. Any ideas on
what could be causing this error message? What can be done to repair the
database in order that this does not occur? Is it improper code written
somewhere? Is it possible that the import of a number of files were done and
only a specified number can be brought in at a time?
Your help is appreciated.When you compile an Access MDE or ADE, it only affects the front-end
-- your forms, code, reports, etc., and not the back end database. I'm
not sure what's causing the error message, but look in your code or at
your connection string.
