Network Management involves issues that are independent of specific hardware or software, including email policies, upgrade planning, backup scheduling and working with managed service providers for Desktop-As-A-Service (DaaS), Software-As-A-Service (SaaS) and the like through the use of tools, coupled with manufacturer standards, best practice guidelines, policies and procedures plus all other relevant documentation. Network management also includes monitoring, alerting and reporting, management reporting, planning for device or service updates, the backup of configurations, the setting of key performance indicators and measures (KPIs/KPMs), associated service level agreements and problem records as part of the IT Service Management (ITSM) framework.

EE,

We are running SolarWinds modules 10.x on 2008R2

The SolarWinds Collector Polling Controller service constantly starts and stops

Event Viewer shows 7031 Service Control Manager Error.

We removed McAfee scanning/HIPS as well as a repair on NPM and the controller in add/remove programs with no change. I'll make the same post on Thwack but figured I'd post here first since I have a subscription.

Thanks in advance

Hi Experts,

I have a question about a subnet used in my network.
I am using this subnet 255.255.248.0
Lets say I have this IP network for my servers 10.1.1.0 - 255.255.255.248.0
and this for my management 10.1.5.0 - 255.255.255.248.0

Is this one broadcast domain ?

I have 2 choices of network setup... Which do you all prefer and why?

MODEM<-static->OPNsense Firewall<-DHCP->HUB<-->SERVER&WORKSTATIONS (OPNsense serves DHCP)

MODEM<-statc->OPNsense Firewall<-static->SERVER<-DHCP->HUB&WORKSTATIONS (Server serves DHCP)

In the second option the server has a WAN Port for the OPNsense appliance and a LAN port to serve the workstations

For the second option I need to know how to setup a static IP between the server and OPNsense appliance

I am looking for a free program like "NetworkView" to discover devices on one subnet .  I just need to be able to save the results...

I have previously used VMWare Application Discovery Manager and CIRBA that 'listened, learned and analysed' what was on the network (in a previous role). That activity gave me a full view of every device, what was on it (apps), what it was (spec), what it talked to (dependencies) etc. It was very useful. ADM appears now to be unavailable, but even if it was I wouldnt have the budget. I want something reliable, intuitive, graphical, unobtrusive, client less etc. Any recommendations or thoughts?

All computers run a program off a network drive but ar random, all computers on the network randomly drops their network drive. None of the computers lose internet access. The server and all computers are Windows 7 Professional.

The last time this happened, I went into network and sharing center to see the attached image yet the computer had access to both the network drives and internet access. My remote access to the computer, and the server was never disconnected.

Computer ----- Yellow Exclamation ! ----- Identifying (Grayed out)----- Red X -----  Internet (Grayed out)

Most recently when they're experiencing problems, they would simply move the mouse on the server. They say the server's monitor would be black and would turn back on.

Steps Already Taken:
The server never sleeps.
The server does not have a screen saver.
The server cannot turn off the network card to save power.
The server is set to never turn off the hard drive.
QOS and IPV6 disabled, IPV4 enabled on all computers. (QOS needs to be disabled for a program to run properly).
Disabled Windows Update Service.
Tested RAM on Server.
Network Cable from server to switch replaced.
Switch replaced.
Drivers and Windows Updated.
Replaced one of the hard drives in the servers raid.
Replaced Secondary Power Supply for Server.


If anyone has any suggestions, that'd be great!NetworkAndSharing.png

I have a desktop that has spiceworks and it is suppose to do software inventory. I would like to use it to pull software information on individual computers.

Is there a way I can do that. It is confusing dashboard and I would like some help.

Thank you.

As part of a change control process I appreciate a change to an existing firewall rule, or the creation of a new rule, should be formally approved by a change control board. At a technical level though, what kinds of questions should the change control board be asking the requestor, i.e. what kinds of risks and analysis would they perform before approving the request.

Also - once you do establish a new firewall rule, is there any useful documentation and information you should provide to detail what the rule is for/does? For a technician experienced in firewalls it may be obvious what a rule is doing ? But from a risk assessment standpoint, is it common for each rule to have some correspoding documentation, and if so what would you expect to be in that documentation. Is there any particular risk in not documenting some background information on each firewall rule?

Also, are there any standard low risk changes to firewalls that you would allow the admins to complete without having to go through formal change control, if so can you provide some examples of these?

It was raised as a risk by a recent audit that our infrastructure team should have documented standard operating procedures for managing firewalls, listing daily/weekly/monthly tasks that are required to effective manage a firewall. This isnt to say that they arent doing these tasks, but their is nothing formal to state what they should be doing - should a new engineer start. I have no experience in managing firewalls myself, but out of curiosity, what kinds of tasks would you expect to see in a firewall management list of tasks. Any specific pointers? Is standard operating procedure the correct term for such a document, or out of interest, what do you refer to them as (which may help for searches to look for other templates online).

Hi Experts
i have mikrotik routerboard with 16 Mbps internet speed
i wanna know how can i split the speed between users
like this scenario
1 user internet speed = 16 Mbps for this user ( if only 1 user exist he will use the whole internet speed )
2 user internet speed = 8 Mbps for every one ( if tow users every one will have 8 Mbps 16/2 )
4 users internet speed = 4 Mbps for every one ( if four users every one will have 4 Mbps 16/4 )

We are doing a Proof of Concept for a network monitoring tool called Unified Infrastructure Management (UIM) by  Computer Associates.

The question I have is what Alerts/Thresholds should I set in regards to Exchange 2013. Do I take the default settings or is there something of value beyond that? Are their items you found that worthy of monitoring that are not in the default setup?  Are there any Windows Server 2012 alerts beyond the default that you would recommend setting up?

Is  Microsoft SCOM a better option?

Any comments of like or dislike in regard to Computer Associates UIM and Exchange 2013?

Thanks for your help!!

For several years I have had allowed an RDP connection to a specific server in my network through the ASA.  It has worked just fine.

Recently, I added a second account to the configuration and the second account is not working.  The first still works fine.  It is only the new one I added that is not allowing an RDP connection through the ASA firewall.

Can anyone find the error in my configuration below?  I am sure I am just missing something.

Here is the config snippet.

object network 74.13.72.173
 host 74.13.72.173
 description This RDP account works

object network 172.14.35.146
 host 172.14.35.146
 description This RDP account does not work

access-list outside_access_in extended permit tcp object-group DM_INLINE_NETWORK_2 host 192.168.250.61 eq 3389

Thank you for any help,

I have a GPO configured for my customers users to map 4 network shares on the DC (Server 2012 Essentials). It seems that these on occasion either take several minutes (10/20/30) to appear after login, or sometimes they do not appear at all.

The GPO is set to replace. Any ideas why this may not work? Seems very intermittent. I was thinking about going down the route of using login scripts instead, but i believe this is not the recommended method.

Also, there is a problem (may not be linked), where the drives will disconnect intermittently. They will reconnect themselves, but the user is given an error that the directory they are looking at is no longer available. Hit refresh, and it comes back again as normal.

Hello:

I am trying to setup a new VLan (VLan 11) on 2 HP ProCurve 24-port Switches.  These 2 switches are connected to each other via 10-GB module.  Each HP ProCurve Switch has its own management IP addressL

- 172.20.1.254 (Default Gateway - VLan-1, IP Routing is enabled)
- 172.20.1.252 (IP Routing is not enabled)

I was able to get VLan-11 working from the 172.20.1.254 Switch; but, not from the 172.20.1.252 switch.  Can someone help me to get the new VLan 11 to work from the .252 switch?

VLan-11 is using the IP Scheme of 172.20.11.0/25


Here is the Startup-Config from .254

Hi I install ACS 5.- in vmware workstation. SecureCRT can login to the ACS and can show running-config through SSH.   But I cannot login its web page. When I entered username and password(acsadmin/password, which is default username and password based on the below protocol link), I got error message "invalid username or password specified". Even if I create a new ACS vm, I still have the same issue. later I got a screenshot which show some certificate issue. Please see picture in attachment. Strange, the document never mentions this issue. Anyone can give some suggestion? Thank you

Hi

Im a little confused with setting up 3 hp switches, there 24 port switchs. I have vlans configured on switch one. I understand truncking from switch 1 to switch 2, however a little confused of getting data to switch 3. Currently port 24 on switch 1 and 2 are tagged as trunck.

Thanks in advance

For any of those involved in IT project management, what is the name of the master document that will list key dates i.e. when the project will ideally be implemented? We work in a risk department and part of the role is to make recommendations and weaknesses in procedures in the IT environment, often these are mitigated by projects, so to be kept on the loop on progress of these projects or target deadlines whereby the team can check for implementation/compliance, it would be useful to get this document, I was hoping to look for some examples online but I am unsure of the key terminology to use.

Whats the best way to test Bandwidth restrictions. I have set HTTP and HTTPS restrictions on a watchguard firewall on 4 different VLANs.

Will a speedtest.net test not work?

Thanks

So I have had a RRAS set up for sometime now. It's been working for about 5 months.

The RRAS and NPS are sitting on a DC that does DHCP. (DC is running 2008 R2)

On the clients, I added a task that adds routing for the local subnets of 10.10.10.0 and 172.28.16.0 (our local LANs)

It was working fine yesterday, and I haven't made any changes but suddenly today remote people couldn't access anything
on the network (although they can connect to the RRAS VPN just fine).

I tested it on my own laptop with the same results.

I'm guessing it has something to do with NPS/NAP, but it's set to grant access and as I said, it was working yesterday.

Any help would be appreciated.

I have uploaded the export of my NPS configuration.

I am also going to restart the server tonight to see if that helps.

Hi,

We currently have access to the network via VPN, this is fine and it works. However when we connect via VPN we are wanting to access servers that are IP restricted to the networks public IP. So we are not able to gain access to these resources.

Is there a way how we can pick up the public IP of the network instead personal public IP. I have looked around and some have suggested to have a proxy setup on a desktop that could be used.

Please can you advise?
