Dealership DMS Support in South Fulton, GA

Dealership DMS Support in South Fulton, GA

Auto dealerships in South Fulton and across Fulton County run their entire operation through a dealer management system. When CDK Global, Reynolds and Reynolds, or Dealertrack goes down or misbehaves, finance deals stall, service write-ups stop, and parts look-ups fail. COMNEXIA has supported automotive dealerships from its Roswell, GA headquarters since 1991, and our managed IT team understands the specific infrastructure that keeps a DMS running reliably and securely inside Georgia dealerships.

What Dealership DMS Support Actually Covers

DMS support is not simply rebooting a server when a salesperson calls. It means maintaining the network, workstations, user accounts, and integrations that the DMS depends on every hour of every business day. For a South Fulton dealership, that translates to several concrete responsibilities.

• Network and DMZ segmentation: CDK Global and Reynolds and Reynolds workstations must sit on isolated VLANs, separated from guest Wi-Fi and from the dealership's general office traffic. We design and document that segmentation using managed switches and firewall rules so that a compromised device in the waiting-room network cannot reach DMS terminals or F&I workstations.
• Endpoint standardization and patch management: Every DMS workstation runs a consistent, documented Windows build. We deploy and monitor patch cycles through NinjaOne RMM, confirming that Windows updates, CDK or Reynolds client software updates, and third-party drivers do not conflict and that no endpoint falls behind the patch window required under FTC Safeguards Rule (16 CFR 314.4).
• Identity and access controls: DMS user accounts are tied to Active Directory or Microsoft Entra ID. We configure conditional access policies in Entra ID so that Dealertrack or CDK logins require multi-factor authentication and are restricted to managed, compliant devices. Role-based permissions are documented and reviewed quarterly.
• Endpoint protection: SentinelOne EDR is deployed on every DMS-connected workstation and server. The agent's behavioral AI detects anomalies specific to DMS processes, such as unexpected scripts querying the Reynolds ERA database, and can isolate the endpoint automatically before lateral movement occurs.
• Secure F&I and CRM integrations: Finance and insurance desks connect the DMS to RouteOne, Dealertrack's credit portal, and CRM platforms such as VinSolutions. We audit each integration point, confirm that API credentials are stored in a secrets manager rather than in plain-text config files, and verify that data flows are encrypted in transit.
• FTC Safeguards Rule compliance support: Georgia dealerships subject to 16 CFR 314.4 must maintain a written information security program, conduct risk assessments, and monitor service provider access. We provide monthly reporting that maps directly to those requirements, documenting patch status, access reviews, and incident log summaries that a dealer principal can hand to an examiner.
• Help desk with ticketing: Every DMS-related issue, from a frozen CDK cashiering screen to a Dealertrack timeout, is logged in our ticketing system with priority classification, technician notes, and resolution time recorded. South Fulton dealership staff call or submit tickets and reach a technician familiar with DMS workflows, not a generalist reading from a script.

A Common South Fulton Dealership Scenario

A multi-rooftop dealership group near Camp Creek Parkway migrates from Reynolds ERA to CDK Drive. During the cutover, F&I workstations need new printer mappings, updated local DNS entries, and revised firewall rules permitting CDK's specific IP ranges. Without documented network architecture and a tested change management process, that migration introduces outages and security gaps. COMNEXIA runs a pre-migration audit, updates VLAN assignments, pushes the new CDK client through NinjaOne to all endpoints simultaneously, and validates that RouteOne integration is authenticating correctly before the first desk manager logs in on opening day.

Why Security-First Matters for DMS Environments

The CDK Global cyberattack in June 2024 disrupted thousands of dealerships nationally, including dealerships across the Atlanta metro, forcing them to process deals on paper for days. South Fulton dealerships that had network segmentation, offline backup procedures, and documented incident response plans recovered faster than those relying on a single point of control. COMNEXIA's security-first approach means those controls exist before an incident, not after.

What Onboarding Looks Like

We begin every dealership engagement with a documented onboarding that inventories all DMS-connected hardware, maps existing VLAN and firewall configurations, identifies unmanaged endpoints, and records every third-party integration credential. That inventory becomes the living baseline for patch management, access reviews, and the written risk assessment required under the FTC Safeguards Rule. There is no black-box handoff. The dealer principal receives a readable network diagram and asset register within the first 30 days.
