2008 R2 SQL Reporting Services 2005

Leave a comment

Well I’ve been having a lot of fun trying to get this installed. For anyone else wondering why the option to install it is greyed out. I’ve discovered that you need the folling installed on the 2008 R2 box:

The most trouble is caused by IIS, and the fact that you need the following bits and pieces in order to make it work.

Component Folder
Static Content Common HTTP Features
Default Document Common HTTP Features
HTTP Redirection Common HTTP Features
Directory Browsing Common HTTP Features
ASP.Net Application Development
ISAPI Extension Application Development
ISAPI Filters Application Development
Windows Authentication Security
IIS Metabase Management Tools
IIS 6 WMI Management Tools

Hopefully, when you have those installed everything should work ok and it will no longer be greyed out. Don’t forget to put SQL SP3 on afterwards!

Android Googlemail Problems

Leave a comment

Recently I’ve not been getting my googlemail on my Hero. No idea why.. it just stopped working. Turns out that if the “space is low” on your phone, it won’t bother syncing. I uninstalled Angry Birds, shed a tear, and then it started to sync again. It would be nice if there was an error message saying that this would happen if the space gets low. Assuming that was the problem of course. It would have saved me hours of messing around! Live and learn…

SCCM OSD 80004005

Leave a comment

I’ve been having a lot of trouble recently with this error. Running an OSD from PXE results in the error 80004005. Nothing specific in the logs other than that error message. I noticed tat if I disabled the install drivers part of the TS, then it worked ok. So clearly one of the drivers was a mess. After a lot of searching I found an article that basically said it was due to the entwork drivers. Now, WinPE includes network drivers, and if this drive is different to the one used by Windows itself, when the driver is updated it will cause a disconnection from the DP. This causes the error. The way around that I have found is to make the advertisement download the content lcoally. This means that it won’t disconnect from the DP, as it’s running locally. Why this is a problem I don’t know. Surely it should jsut try to connect again, but I guess not.

There is an article here on Windows Noob (very good site) http://www.windows-noob.com/forums/index.php?/topic/1688-nic-devices-that-require-a-special-driver-for-winpe-may-cause-a-configmgr-task-sequence-to-fail/ that explains it a bit more

Kerberos Authentication Issues

Leave a comment

Troubleshooting Kerberos issues is one of the least fun things to do. Mostly, because when it fails, there will be no error message. It will silently revert to NTLM, and you won’t know why.

I’ve been having a bit of fun getting our new Sharepoint 2010 install to work. I’ve set the SPNs correctly by using “setspn -a HTTP/thesharepoint.domain.co applicationPoolAccount”. This worked fine for one site, however the second one was still reverting to NLTM. Why?? I enabled kerberos tracking on the servers as per this KB – 262177. No errors that were relevant were recorded. I even started packet tracing the kerberos tickets. It was then that I noticed this error “KRB_ERR_S_PRINCIPAL_UNKNOWN” . Strange.. I re-checked, and the SPN (service principle name) was added so why is it unknown? After several hours of fiddling, I realised it was a duplicate SPN. Now, why the error message can’t say that, I don’t know. Infuriating. I found the duplicate SPN by running the following command:
ldifde -f check_SPN.txt -t 3268 -d “” -l servicePrincipalName -r “(servicePrincipalName=HOST/mycomputer*)” -p subtree
Obviously change “HOST\mycomputer” to the SPN you are checking. Delete the SPN with “setspn -d”. Having done this, kerberos now works well…
