Antti Posted March 28, 2011 Report Share Posted March 28, 2011 Hi, Are you getting VSS error 8194 on Windows Server 2008 (ours are R2)? We are (on all of them), and I know many others are, too. I have an open support case, but I'm having difficulties in getting my message through. The error (see below) is probably caused by MS or Retrospect. According to MS Technet article (link below) this is caused by the application. So, help me and yourself by answering to this thread. Thank you! ----- Volume Shadow Copy Service error: Unexpected error querying for the IVssWriterCallback interface. hr = 0x80070005, Access is denied. . This is often caused by incorrect security settings in either the writer or requestor process. ----- Some information on MS Technet. Quote Link to comment Share on other sites More sharing options...

Are there any error message shows as followed?

You may be able to workaround the problem by doing the following: - Start | Run and type dcomcnfg and hit Enter key - Expand Component Services - Expand Computers | My Computer - Right Click on My Computer and choose Properties - Select COM Security - Select Edit Default on Access Permission - Add the Cluster Service Domain account with Local Access and Remote Access allowed If this does not work then add in the following also: - Start | Run and type dcomcnfg and hit Enter key - Expand Component Services - Expand Computers | My Computer | DCOM Config - Select your Ultrabac client exe - Right click and select Properties - Click on Security tab - Select Customize option for Access Permission and click Edit button - Add the Cluster Service Domain Account to grant access Could also be that the 32 bit requestors won't work with 64 bit VSS services.

Antti Posted March 28, 2011 Author Report Share Posted March 28, 2011 link from social technet may help: I wasn't asking for tech help and you actually posted the same link I did. About the advice on the other link then: I would not change any permissions on servers unless the OS/software vendor says so. Roxio should mention these errors in the documentation. If workarounds are needed, they have to be documented. If nothing needs to be done, then Roxio tech support should tell me that these messages can be ignored. Whatever the case, if the product has been tested with the OS in question, these error messages should have been spotted and the problem fixed.

a2fb0a10-2342-4e1a-bd36-850f60265cfe Posted March 28, 2011 Report Share Posted March 28, 2011 just trying to help plus your technet link doesnt work for me Quote Link to comment Share on other sites More sharing options...
Antti Posted March 30, 2011 Author Report Share Posted March 30, 2011 just trying to help plus your technet link doesnt work for me Thanks, sincerely, for trying. I don't think this can be solved by users, though. I was after getting some pressure from the community on Roxio, so they would fix this. I'm certain that most if not all are getting these errors on 2k8R2. On the old forum there were at least this and this on the subject. I'm not too satisfied with the tech support, but I got an answer after two weeks of trying. They "are confident that there is no cause for concern". Ok, there is not much else I can do about it, but at least I have an answer and the support case to back this up. Quote Link to comment Share on other sites More sharing options...
a2fb0a10-2342-4e1a-bd36-850f60265cfe Posted March 30, 2011 Report Share Posted March 30, 2011 I have yet to test the product with w2k8 r2...currently testing on the 32 bit version and in the process of creating a list of questions to be hopefully answered by support or the forum:) Quote Link to comment Share on other sites More sharing options...
641807c2-7ead-49db-8aed-9af1f6f28f12 Posted April 6, 2011 Report Share Posted April 6, 2011 Yes, we get this on our servers as well. Not just 2k8, on 2k3 servers as well. Quote Link to comment Share on other sites More sharing options...
robvil Posted April 7, 2011 Report Share Posted April 7, 2011 Yes, we get this on our servers as well. Not just 2k8, on 2k3 servers as well. we still see these errors on windows 2008 and newer systems. It is only when using retrospect we get these, using MS build in backup tool do not log these entries, so hallo! Come retrospect - it is a issue with your software.
