I'm having issues getting our network devices to work with SNMP v3 and there's not much online in the way of troubleshooting v3.
I went ahead and switched to v2 just to see it work and does show up as healthy now, however, it doesn't appear to pull any CPU/Memory or interface data even though it shows CERTIFIED and enumerated the Vender as PA-5000 series. The Network Summary view shows the interfaces with a green empty circle as if it's not being monitored. Firewalls are obviously fine since it enumerated the OID Tree and discovered everything.

Do we need SNMP port 162 in addition to 161 or could this be another issue?

Hi Expert,

One of our development team were trying to loading the data in their test database from their application portal.

They can attach file into the database but they got the following error.

"Timeout during database update. The operation has been accepted by the server and will usually complete successfully."

They are able to load the file successfully but don't want application user to see this.

Here is my question, is there any option to set up timeout for the database level. They set up the file size from application side only for 20 MB

Please help
is yelp account for business free ?

if yes can someone send me the correct link please ?

thank you
I have a current storage device which is clustered between 4 servers (2 application servers, and 2 database servers) There are 2 quorum disks one is attached to the database and the other is attached to the application sever - all of this resides on the SAN unit. I have 10 disks on my application server and 3 disks on my SQL server.  I've tried with the vendor 2 times and he's failed to migrate the cluster to the new storage unit.  Let me just say the new storage unit is set up exactly like the old storage unit and all the data is copied.  Can someone give me some information on the method to attach the new storage unit and detach from the old storage unit?  I think you have to break the cluster 1st because if you don't the drives will just fail over and apparently the contractor doesn't understand the concept of a cluster.
Hi Experts, we have a client with an old network system. There are 15 users in Sussex and 3 users in site London.
At the sussex main site there is 1 x sbs 2003 that runs active diretory, dns , dhcp, exchange (pop collector) and files. Also they have on this server sage payroll.

They also have 1 x windows 7 machine that runs sage adm (multiple different versions) and Iris.
Ix windows 7 machine also servers as a windows RDP server for the London office , 3 users.
They log into access files and the apps.

They are considering going to Office 365 and want to explore how they can have a better , secure system.
We are looking at proposing Server 2012 DC , and an Apps server for Sage, Iris and a documents storage program they use.
We are considering a VM server to run this , just wondered if we could get some feedback and some advice on best approach for this.
I've inherited someone's undocumented setup, and I'm a first-timer who is learning OTJ.  Weblogic version is 10.3.2; the services are Forms and Reports. My startup sequence, at a high level, is to fire up three admin servers (startWebLogic), then three node managers (startNodeManager), followed by numerous user projects (startMangedWebLogic). Lastly, I start my oid and fr instances with opmnctl.

I've become a little familiar with the startup sequence, why Admin has to load before the managed services. Yea. My goal is to understand why there are three admin servers and three node managers (set up by persons before me, long since gone). The domains are for OID, OAM, and FR (forms).

Please help me understand whether this arrangement is healthy and if not, how to improve on it.  TIA.
We are migrating away from a key production application, but I am wondering how to handle support for the remainder of the year?

If you have done any major application migrations, how have you handled support on the legacy system?
- only break/fix support?
- no new reports?

What did you find as guidelines that worked for you?

Is the attached (fr our financl services apps vendor) for  apps API ?

Is OCA3 now deprecated & should it be replaced with OCA4?

Hello Experts - I have just started a new contract job as a Sys Admin but there is no hand-over as the previous person has left already. There is very little documentation, the docs all look out of date or incomplete & it's a very small team so no-one within the team can tell me exactly how many applications we have (50'ish best guess!!), what they are, versions, etc, etc. Not ideal.

I really need to find a way to audit my VMWare ESXi V5.5 environment & give me detailed info on my applications, the infrastructure side is much easier to work out. The type of application info I need is what apps & the versions, what databases are they using, size of databases, maintenance/backup schedule info & most crucial of all - what application interfaces do I have. I don't know what (if any) middleware they have so the application interface info is the biggest concern.

I'm thinking apps such as LabTech, SpiceWorks & Puppet Enterprise run as a 30 day trial will give me infrastructure info but I don't know if they also provide that detailed application audit info I need. I know VMware vSphere can give me infrastructure info on the VMware farm but I don't think it provided application info but I could be wrong.

My on premise VMware farm has 62 servers Windows 2008 & 2012 & RHEL V6. I know my databases are a mix of MS SQL & Oracle. The apps cover ERP, Payroll, Retail, Business Intelligence, Supply Chain, Manufacturing plus the usual Microsoft AD, Exchange, etc, etc.

Do you have relevant details to create Developer account to

Hi Team,

What is the Best way to keep copy of live production application(.net plus something else) and database (sql server) servers in different places?


My client is proving a portal for their customer as part of their services and which is also providing payment gateway etc...

But my client has engaged a trusted third party developer who has built this application and has full control over it even the hosting server(amazon), application code and database etc...

Even though a legal strong agreement in place my client want to keep a control and monitor and copy of the above application and database server somewhere outside(amazon) or at their office!
Just to make sure that even in future if developer shutdown portal serve their customers!

Now questions are...

- How can we keep a live copy of application and database server ?
Best way to handle such a situation!
- How can we make sure or check whatever the application code changes made by developer are updating on other server?

- What is the best way to sync live application and database servers in two different places? And how quickly or any in built sync features (high availability) are there in sql server?

Note: Developer will agree for any term as he's just working for my client!
Preface - I realize there are lots of programs for backup that have lots of features that Windows Server backup does not have.  However I am not interested in them as a response to this post - I write this as some times when I ask a question about a product I get a lot of tips of alternative products - at this point I don't want alternative suggestions to Windows Server Backup. What I want is  somebody/somebodies who have a lot of expertise with Windows Server backup to respond to these questions.

It seems that Windows Server backup' self-manages when to clean up older copies/when to create new full backups on target media. What is the criteria it uses?  We usually backup to locally attached USB drives and we seem to have lots of situations where the disk gets full and backups can't be made to it anymore. Often this happens when Windows Server backup thinks it's time for a full backup - it tries to do one and then it runs out of space.  I am just trying to figure out what it's self management algorithm is as it doesn't seem to work all the time.  We want to know what it's 'thinking' as it goes about its business.

Another question I have is what happens when you have a backup drive that has been used by a backup job for some time and then you create a new job using the same backup unit as the target - will Windows Server Backup 'start' from where the previous job left off? Or will it wipe all the previous backups?

For either of the above does it make a difference if …
Dear All,

What exactly does it mean if we get the below error on trying to access a banking application:

TCP Error Code: 10061:- No connection could be made because the Target machine actively refused it ip:x.x.x.x : 443

Any help would be greatly appreciated.

Our company host most of our systems internally, some of them being critical systems and as such they have their own support teams just to look after them etc.  One of the things we are considering at the moment to reduce costs is to outsource some of these systems to a third party.  As a result, these support teams will inevitable have to be made redundant.

The systems that concern me the most are our financial systems (SAP).  These support staff obviously have an excellent understanding of the system, no doubt better than anyone else in the company.  My concern is that these support staff will become disgruntled if they catch wind of any ideas (whether we go through with them or not but especially if we do) and could potentially, using their knowledge, either committee fraud or malicious acts against the system or data.

How can we as a company protect the system and its data against such acts by staff who might be adamant on causing issues?  Perhaps we can’t do this 100% but would at least need to be able to identify it after the event.

What I plan on doing firstly is reviewing system access to ensure that everyone’s access is based on the principle of least privilege.  Then ensuring that audit logs are capturing everything and that these logs are regularly reviewed to identify any suspicious activity.

Is there anything else we can do?
I have a Windows 2012 domain.  I have two "generic" accounts that need access to the Internet and to networked printers, but I do not want them to have access to any file shares or server applications.  Network drives are mapped automatically and can be seen by the generic account users.  There is a desktop shortcut to a server application via RDP that is on every PC.

Is there a way to centrally make it so these generic users cannot see, or if they can see, cannot access the network drives and server applications?  I do not want to have to take the time to go into every file share.  I would rather do this on the user side, if possible.

Thank you
I have an older Server 2008 R2 application server (IIS 6 and 7 are installed, I know it was a mail relay and a licensing server for our engineering program, but not sure what else) in my domain that I'm attempting to sunset and remove.  My issue is that I've been here a year and I'm still stumbling onto undocumented applications and processes in my environment, and I fear removing the server and finding out later on that there was an old app, piece of manufacturing equipment, MFP, etc. that depended on something that was running on the server.

What's my best option for determining who or what might be connecting to this box, and for what purpose?

My first thought is wireshark, but I'm not too experienced with the app, so I don't know if this is my 'best' option or not.  I could also just shut the thing down and wait for an outcry, but I really hate the impression that type of move will give to my users (if it turns out that this is hosting some critical process).

Any advice would be greatly appreciated!
