Dealership DMS Support in Tucker, GA

Dealership DMS Support in Tucker, GA: Managed IT for CDK, Reynolds & Reynolds, and Dealertrack

Auto dealerships in Tucker and across DeKalb County run on their Dealer Management System. When CDK Global goes down during a Saturday sales push, when a Reynolds and Reynolds integration breaks after a Windows update, or when Dealertrack slows to a crawl during F&I closing, the cost is immediate and measurable. COMNEXIA, headquartered in Roswell, GA and working with dealerships since 1991, provides hands-on DMS support that keeps those platforms stable, secure, and compliant with the FTC Safeguards Rule (16 CFR Part 314).

What Dealership DMS Support Actually Covers

DMS support is not generic helpdesk work. It requires understanding the specific communication paths between your DMS, your F&I platform, your CRM, and your OEM data feeds. COMNEXIA engineers map every integration before touching a configuration. For CDK Global environments, that means documenting the CDK Drive API endpoints and the Windows Server instances hosting local CDK components. For Reynolds and Reynolds ERA-IGNITE shops, it means validating the ERA server communication ports and confirming that endpoint updates do not break the REYREY print driver stack. For Dealertrack DMS, it means confirming that browser-based access routes correctly through your network without proxy conflicts that cause session drops mid-deal.

Network Segmentation: Protecting the DMZ Between DMS and Dealership Traffic

The FTC Safeguards Rule requires dealerships to protect customer nonpublic personal information (NPI) with a documented information security program. One of the most direct technical controls is proper network segmentation between your DMS environment, your guest Wi-Fi, your service department terminals, and your showroom floor devices. COMNEXIA configures VLAN-based segmentation on your switching infrastructure, places DMS servers and F&I workstations in a dedicated segment behind firewall policy rules, and restricts lateral movement using access control lists. This architecture prevents a compromised loaner-car kiosk from reaching the server handling Dealertrack customer credit applications.

On the endpoint side, COMNEXIA deploys SentinelOne EDR across DMS-connected workstations, providing behavioral detection that catches threats not yet in a signature database. Microsoft Entra ID conditional access policies enforce multi-factor authentication for any staff account that touches the DMS or F&I portal, meeting the access-control requirements outlined in 16 CFR 314.4(c).

Patch Management and DMS Compatibility: The Problem Most MSPs Miss

Unmanaged Windows updates are one of the most common causes of DMS outages at dealerships. A cumulative update that ships on Patch Tuesday can break a CDK Global local component or conflict with a Reynolds and Reynolds ERA print service. COMNEXIA uses NinjaOne RMM to control update deployment across every endpoint and server in the dealership. Updates are staged in a test group first, validated against DMS functionality, and then pushed to production workstations during off-hours windows. This process means your service advisors are not staring at a broken DMS on Monday morning because an uncontrolled update ran over the weekend.

What COMNEXIA Delivers for Tucker Dealerships

• Full inventory and documentation of DMS-connected endpoints, servers, and integration points before any change is made
• VLAN segmentation and firewall rule configuration isolating DMS and F&I traffic from general dealership network segments
• SentinelOne EDR deployment on all DMS-connected workstations with policy tuned to allowlist known DMS processes
• Microsoft Entra ID conditional access enforcing MFA for CDK, Reynolds and Reynolds, and Dealertrack portal logins
• NinjaOne RMM-managed patch staging that validates compatibility with DMS components before production rollout
• Ticketing through a documented helpdesk so every DMS-related issue has a logged record, response history, and resolution note
• Monthly reporting showing patch compliance rates, endpoint health, and open/closed tickets relevant to DMS operations
• FTC Safeguards Rule gap assessment mapping your current controls against the 16 CFR 314.4 requirements for access control, encryption, and incident response

A Scenario Common to DeKalb County Dealerships

A Tucker-area franchise dealership running Reynolds and Reynolds ERA-IGNITE contacts COMNEXIA after experiencing repeated DMS session drops. COMNEXIA's onboarding process captures the full network topology, identifies that service department devices share a subnet with the ERA server, and confirms that an unmanaged switch in the service bay is flooding broadcast traffic into that segment. COMNEXIA reconfigures the switching layer to isolate the ERA server onto a dedicated VLAN, deploys NinjaOne agents on all 22 endpoints, and sets patch deployment to a managed schedule. Session drops stop. The dealership now has documented evidence of its network controls, which directly supports its FTC Safeguards Rule compliance documentation.

Serving Tucker and the Greater Atlanta Metro

COMNEXIA is based in Roswell, GA and has supported businesses in DeKalb County and across the Atlanta metro for 35 years. Tucker dealerships get direct access to engineers who know the specific integration behaviors of CDK Global, Reynolds and Reynolds, and Dealertrack, not a generalist helpdesk reading from a script.

If your dealership is running a DMS without documented network segmentation, managed patch control, or MFA enforcement, those are gaps the FTC Safeguards Rule expects you to close. Call COMNEXIA at (877) 600-6550 to schedule a DMS environment review and find out exactly where your exposure is.
